SY89297U2.5/3.3V, 3.2Gbps Precision CML Dual-Channel Programmable DelayPrecision Edge is a registered trademark of Micrel, Inc.Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 (408) 944-0800 • fax + 1 (408) 474-1000 •General DescriptionThe SY89297U is a DC-3.2Gbps programmable, two-channel delay line. Each channel has a delay range from 2ns to 7ns (5ns delta delay) in programmable increments as small as 5ps. The delay step is extremely linear and monotonic over the entire programming range, with 15ps INL over temperature and voltage.The delay varies in discrete steps based on a serial control word provided by the 3-pin serial control (SDATA, SCLK, and SLOAD). The control word for each channel is 10-bits. Both channels are programmed through a common serial interface. For increased delay, multiple SY89297U delay lines can be cascaded together.The SY89297U provides two independent 3.2Gbps delay lines in an ultra-small 4mm x 4mm, 24-pin QFN package. For other delay line solutions, consider the SY89295U and SY89296U single-channel delay lines. Evaluation boards are available for all these parts.Datasheets and support documentation can be found on Micrel’s web site at: .Precision Edge ®Features• Dual-channel, programmable delay line• Serial programming interface (SDATA, SCLK, SLOAD) • Guaranteed AC performance over temperature and voltage:– > 3.2Gbps/1.6GHz f MAX • Programming Accuracy: – Linearity: −15ps to +15ps INL – Monotonic: −5ps to +25ps– Resolution: 5ps programming increments • Low-jitter design: 1ps RMS typical random jitter • Programmable delay range: 5ns delay range • Cascade capability for increased delay • Flexible voltage operation:– V CC = 2.5V ± 5% or 3.3V ± 10% • Industrial temperature range: −40°C to +85°C • Available in 24-pin (4mm x 4mm) QFNApplications• Clock de-skewing • Timing adjustments • Aperture centering • System calibrationMarkets• Automated test equipment• Digital radio and video broadcasting • Closed caption encoders/decoders • Test and measurementOrdering Information(1)Part Number Package Type Operating Range Package Marking Lead FinishSY89297UMG QFN-24 Industrial 297U with Pb-Free Bar Line Indicator Pb-Free NiPdAuSY89297UMGTR(2)QFN-24 Industrial 297U with Pb-Free Bar-Line Indicator Pb-Free NiPdAuNotes:1.

QA and /QA are the delayed product of INA and /INA. Each input is internally terminated to VTA through a 50Ω resistor (100Ω across INA and /INA).3 VTA Input A Termination Center-Tap: Each side of the differential input pair terminates to this pin.This pin provides a center-tap to a termination network for maximum interface flexibility. See“Input Interface Applications” section. 4 VTBInput B Termination Center-Tap: Each side of the differential input pair terminates to this pin. This pin provides a center-tap to a termination network for maximum interface flexibility. See “Input Interface Applications” section. 5 6INB /INBChannel B Differential Input: INB and /INB pins receive the Channel B data. QB and /QB are the delayed product of INB and /INB. Each input is internally terminated to VTB through a 50Ω resistor (100Ω across INB and /INB).7 VREF-ACReference Voltage Output: For AC-coupled input signals, this pin can bias the inputs IN and /IN. Connect VREF-AC directly to the VT input pin for each channel. De-couple to V CC using a0.01µF capacitor. Maximum sink/source current is ±0.5mA. For DC-coupled input applications, leave VREF-AC pin floating. 8, 11, 20GND, Exposed PadNegative Supply: Exposed pad must be connected to a ground plane that is the same potential as the ground pins.9 /ENACMOS/TTL-Compatible Enable Input: When the /ENA pin is pulled HIGH, QA is held LOW and /QA goes HIGH after the programmed delay propagates through the part. /ENA contains a 67k Ω pull-down resistor and defaults LOW when left floating. Logic threshold level is V CC /2 10 /ENBCMOS/TTL-Compatible Enable Input: When the /ENB pin is pulled HIGH, QB is held LOW and /QB goes HIGH after the programmed delay propagates through the part. /ENB contains a 67k Ω pull-down resistor and defaults LOW when left floating. Logic threshold level is Vcc/2 12, 15, 16, 19VCC Power Supply: Bypass each supply pin with 0.1µF//0.01µF low-ESR capacitors. See DC Electrical Characteristics table for more details. 2.5V ±5% or 3.3V ±10%.13 14 /QB QB CML Differential Output: QB and /QB are the delayed product of INB, /INB. CML outputs are terminated at the destination with 100Ω across the pair. See “CML Output Termination” section.17 18/QA QACML Differential Output: QA and /QA are the delayed product of INA, /INA. CML outputs are terminated at the destination with 100Ω across the pair. See “CML Output Termination” section.23 22SCLK SDATACMOS/TTL-compatible 3-pin serial programming control inputs: The 3-pin serial control sets each channel’s IN to Q delay. DA(0:9) control channel A delay. DB(0:9) control channel B. To program the two channels, insert a 20-bit word (DA0:DA9 and DB0:DB9) into SDATA and clock in the control bits with SCLK. Maximum input frequency to SCLK is 40MHz. Data is loaded into the serial registers on the L-H transition of SCLK. After all 20-bits are clocked in, SLOAD latches the new delay bits. These pins have internal pull-downs at the inputs. See “ACElectrical Characteristics” for delay values. Logic threshold level is Vcc/2. SCLK and SDATA contain a 67k Ω pull-down resistor and default LOW when left floating.24 SLOADCMOS/TTL-compatible 3-pin serial programming control input: SLOAD controls the latches that transfer scanned data to the delay line. These latches are transparent when SLOAD is high. Data transfers from the latch to the delay line on a L-H transition of SLOAD. SLOAD has to transition H-L before new data is loaded in the scan chain. When SLOAD is high, the latches are transparent and SCLK cannot switch. Otherwise, new data will immediately transfer to the scan chain. Logic threshold level is Vcc/2. SLOAD contains a 67k Ω pull-down resistor and defaults LOW when left floating. 21 SOUTCMOS/TTL-compatible output: This pin is used to support cascading multiple SY89297U delay lines. Serial data is clocked into the SDATA input and is clocked out of SOUT into the next SY89297U delay line. SOUT pin includes an internal 550Ω pull-up resistor.Absolute Maximum Ratings(1)Supply Voltage (V CC) .................................. –0.5V to +4.0V Input Voltage (V IN) .......................................... –0.5V to V CC CML Output Voltage (V OUT)… .......

Duty cycle skew guaranteed only for differential operation measured from the cross point of the input to the crosspoint of the output.9. INL (Integral Non-Linearity) is defined from its corresponding point on the ideal delay versus D[9:0] curve as the deviation from its ideal delay. Themaximum difference is the INL. Theoretical Ideal Linearity (TIL) = (measured maximum delay – measured minimum delay) ÷ 1023. INL = measured delay – (measured minimum delay + (step number x TIL)).10. SCLK has to transition L-H a setup time before the SLOAD H-L transition to ensure the valid data is properly latched. See timing diagram "Setupand Hold Time: SCLK and SLOAD.”11. This setup time is the minimum time that /EN must be asserted prior to the next transition of IN / /IN to prevent an output response greater than±75 mV to that IN or /IN transition. See timing diagram Setup, Hold and Release Time: IN and /EN."12. SCLK has to transition L-H a hold time after the SLOAD H-L transition to ensure that the valid data is properly latched before starting to load newdata. See timing diagram "Setup and Hold Time: SCLK and SLOAD.”13. This hold time is the minimum time that /EN must remain asserted after a negative going transition of IN to prevent an output response greater than+75mv to the IN transition. See timing diagram “Setup, Hold, and Release Time: IN and /EN.”14. This release time is the minimum time that /EN must be de-asserted prior to the next IN / /IN transition to affect the propagation delay of IN to Qless than 1ps. See timing diagram “Setup, Hold, and Release Time: IN and /EN.”15. Cycle-to-cycle jitter definition: The variation of periods between adjacent cycles over a random sample of adjacent cycle pairs.T jitter_cc = T n – T n+1, where T is the time between rising edges of the output signal.16. Total jitter definition: With an ideal clock input, no more than one output edge in 1012 output edges will deviate by more than the specified peak-to-peak jitter value.17. Random jitter definition: Jitter that is characterized by a Gaussian distribution, unbounded and is quantified by its standard deviation and mean.Random jitter is measured with a K28.7 comma defect pattern, measured at 1.5Gbps.Timing DiagramsFigure 1.

Fluke 8920A、8921A和8922A多功能电压计说明书
FLUKE 8922A8920A, 8921A & 8922AAutorangingFluke's autoranging feature allows you to carry out your testing without having to change ranges manually. A range can be placed on HOLD or manually stepped up to a higher range. On HOLD, the meter will remain in a given range regardless of changes in input levels. On STEP UP, the meter will increase ranges step-by-step until the switch is released. Peaking/Dipping MeterIn addition to an accurate digital display, all Fluke Voltmeters in the 8920-Series feature an analog meter for peak and null voltage adjustments. The meter indicates O to 100 percent full scale in each range.Linear Analog OutputModels 8920A and 8922A are equipped with a rear panel output for driving X-Y or st d p chart recorders, delivering voltages proportional to the display count. A 2-volt level equals 2000 counts, a 1-volt level equals 1000 counts, etc. This feature is not available on Model 8921A. AccuracyFluke Digital Voltmeters avoid the possibilities for error so common in analog meters. The digital displays eliminate the likelihood of misreading the meter due to viewing angle problems of parallax common with analog meters. Also, the accuracy of 8920-Series Voltmeters is specified as a percent of reading rather than as percent of full scale.Percent of reading accuracy does not degrade for measurements at the low end of a scale. Front panel switching offers a choice of readings in dB or volts.Technical SpecificationsThe a ccuracy s pecifications b elow apply from 9% to 100% of full scale and from 18°C to 28°C for 90 days.

Read and follow all of Whelen’s written instructions when installing or using this device. Emergency vehicles are often operated under high speed stressful conditions which must be accounted for when installing all emergency warning devices. Controls should be placed within convenient reach of the operator so that they can operate the system without taking their eyes off the roadway. Emergency warning devices can require high electrical voltages and/or currents. Properly protect and use caution around live electrical connections.Grounding or shorting of electrical connections can cause high current arcing, which can cause personal injury and/or vehicle damage, including fire. Many electronic devices used in emergency vehicles can create or be affected by electromagnetic interference. Therefore, after installation of any electronic device it is necessary to test all electronic equipment simultaneously to insure that they operate free of interference from other components within the vehicle. Never power emergency warning equipment from the same circuit or share the same grounding circuit with radio communication equipment. All devices should be mounted in accordance with the manufacturer’s instructions and securely fastened to vehicle elements of sufficient strength to withstand the forces applied to the device. Driver and/or passenger air bags (SRS) will affect the way equipment should be mounted. This device should be mounted by permanent installation and within the zones specified by the vehicle manufacturer, if any. Any device mounted in the deployment area of an air bag will damage or reduce the effectiveness of the air bag and may damage or dislodge the device. Installer must be sure that this device, its mounting hardware and electrical supply wiring does not interfere with the air bag or the SRS wiring or sensors. Mounting the unit inside the vehicle by a method other than permanent installation is not recommended as unit may become dislodged during swerving; sudden braking or collision. Failure to follow instructions can result in personal injury. Whelen assumes no liability for any loss resulting from the use of this warning device. PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF EMERGENCY PERSONNEL AND THE PUBLIC.Warnings to UsersWhelen’s emergency vehicle warning devices are intended to alert other operators and pedestrians to the presence and operation of emergency vehicles and personnel. However, the use of this or any other Whelen emergency warning device does not guarantee that you will have the right-of-way or that other drivers and pedestrians will properly heed an emergency warning signal. Never assume you have the right-of-way. It is your responsibility to proceed safely before entering an intersection, driving against traffic, responding at a high rate of speed, or walking on or around traffic lanes. Emergency vehicle warning devices should be tested on a daily basis to ensure that they operate properly. When in actual use, the operator must ensure that both visual and audible warnings are not blocked by vehicle components (i.e.: open trunks or compartment doors), people, vehicles, or other obstructions. It is the user’s responsibility to understand and obey all laws regarding emergency warning devices. The user should be familiar with all applicable laws and regulations prior to the use of any emergency vehicle warning device. Whelen’s audible warning devices are designed to project sound in a forward direction away from the vehicle occupants. However, because sustained periodic exposure to loud sounds can cause hearing loss, all audible warning devices should be installed and operated in accordance with the standards established by the National Fire Protection Association.Safety FirstThis document provides all the necessary information to allow your Whelen product to be properly and safely installed. Before beginning the installation and/or operation of your new product, the installation technician and operator must read this manual completely. Important information is contained herein that could prevent serious injury or damage.WARNING: This product can expose you to chemicals including Methylene Chloride which is known to the State of California to cause cancer, and Bisphenol A, which is known to the State of California to cause birth defects or other reproductive harm.

Chemlok® 289/290 Adhesive Technical Data SheetChemlok® 289/290 adhesive is an adhesive system designed for bonding rubber linings to steel, stainless steel, aluminum, titanium, wood and other substrates. It is composed of a mixture of polymers, organic compounds and mineral fillers dissolved or dispersed in an organic solvent system.Chemlok 289/290 adhesive is suitable for cure by autoclave, open steam or chemical techniques. Features and Benefits:Versatile – bonds many rubber compounds to a variety of substrates.Easy to Apply – applies easily by brush, roll coat or spray methods.Corrosion Resistant – provides excellent corrosion resistance.Application:Surface Preparation – Thoroughly clean metal surfaces prior to primer application. Remove protective oils, cutting oils and greases by solvent degreasing or alkaline cleaning. Remove rust, scale or oxide coatingsby grit blasting. Use steel grit to blast clean steel and other ferrous metals. Use aluminum oxide, sand or other nonferrous grit to blast clean stainless steel, aluminum and other nonferrous metals.For further detailed information on surface preparationof specific substrates, refer to Chemlok Adhesives application guide.Mixing – Thoroughly stir primer and covercoat before use, and agitate sufficiently during use to keep dispersed solids uniformly suspended.Chemlok 289 primer and Chemlok 290 covercoatare normally used full strength for brush or roll coat applications. For spray application, dilute Chemlok 289 primer with a 1:1 MEK/xylene mixture; dilute Chemlok 290covercoat with xylene or toluene.Applying – Separately apply primer and covercoat by brush, roll coat or spray methods. For best results, apply adhesive system to surfaces with temperatures less than 38°C (100°F).Regardless of application method, the recommended dry film thickness ranges are:Chemlok 289 10.2-22.9 micron (0.4-0.9 mil) Chemlok 290 2.5-15.2 micron (0.1-0.6 mil) Optimal dry film thicknesses of primer and covercoat vary based on the end-use application (i.e., substrate, elastomer, application method, cure method, service environment, etc.).Drying/Curing – Allow primer to air-dry for 30-60 minutes before applying covercoat to prevent solvent entrapment and subsequent blistering.If parts applied with Chemlok 289 primer remain uncoated for more than seven days, primer must be reapplied prior to Chemlok 290 covercoat application. Parts coatedwith Chemlok 290 covercoat can be stored for up to seven days prior to rubber layup without affecting bond performance if protected from sunlight exposure.
