FM RECEIVER CIRCUIT FOR BATTERY SUPPLY
DESCRIPTION
The SC1088 is a bipolar integrated circuit for use in mono portable and pocket radios. It is used when a minimum of perpheral components (of small dimensions and low costs) is important. The circuit contains a frequency-locked-loop(FLL) system with an intermediate frequency(IF) of about 70kHz. Selectivity is achieved by active RC-filters. De-tuning related to the IF and too weak input signal is suppressed by the mute circuit.

Device composition includes high-temperature solder (Pb >85%), which is exempted from the RoHS directive.Audio Amplification Transistor 2SC6011ABecause reliability can be affected adversely by improper storage environments and handling methods, please observe the following cautions.Cautions for Storage• Ensure that storage conditions comply with the standard temperature (5°C to 35°C) and the standard relative humidity(around 40 to 75%); avoid storage locations that experienceextreme changes in temperature or humidity.• Avoid locations where dust or harmful gases are present and avoid direct sunlight.• Reinspect for rust on leads and solderability of products that have been stored for a long time.Cautions for Testing and HandlingWhen tests are carried out during inspection testing and otherstandard test periods, protect the products from power surgesfrom the testing device, shorts between adjacent products, and shorts to the heatsink.Remarks About Using Silicone Grease with a Heatsink• When silicone grease is used in mounting this product on a heatsink, it shall be applied evenly and thinly. If more siliconegrease than required is applied, it may produce stress.• Coat the back surface of the product and both surfaces of the insulating plate to improve heat transfer between the product and the heatsink.• Volatile-type silicone greases may permeate the product and produce cracks after long periods of time, resulting in reducedheat radiation effect, and possibly shortening the lifetime of theproduct.• Our recommended silicone greases for heat radiation purposes, which will not cause any adverse effect on the product life, areindicated below:Type SuppliersG746Shin-Etsu Chemical Co., Ltd.YG6260GE Toshiba Silicone Co., Ltd.SC102Dow Corning Toray Silicone Co., Ltd.Heatsink Mounting Method• Torque When Tightening Mounting Screws. Thermal resistance increases when tightening torque is low, and radiation effects are decreased. When the torque is too high, the screw can strip, the heatsink can be deformed, and distortion can arise in the product frame.To avoid these problems, observe the recommended tightening torques for this product package type, TO-3P (MT-100): 0.686 to 0.882 N•m (7 to 9 kgf•cm).• Diameter of Heatsink Hole: < 4 mm. The defl ection of the press mold when making the hole may cause the case material to crack at the joint with the heatsink. Please pay special attention for this effect.Soldering• When soldering the products, please be sure to minimize the working time, within the following limits:260±5°C 10 s350±5°C 3 s• Soldering iron should be at a distance of at least 1.5 mm from the body of the productsElectrostatic Discharge• When handling the products, operator must be grounded.Grounded wrist straps worn should have at least 1 MΩ ofresistance to ground to prevent shock hazard.• Workbenches where the products are handled should begrounded and be provided with conductive table and floor mats.• When using measuring equipment such as a curve tracer, the equipment should be grounded.• When soldering the products, the head of soldering irons or the solder bath must be grounded in other to prevent leak voltagesgenerated by them from being applied to the products.• The products should always be stored and transported in our shipping containers or conductive containers, or be wrapped inaluminum foil.Audio Amplification Transistor 2SC6011AThe products described herein are manufactured in Ja p an by Sanken Electric Co., Ltd. for sale by Allegro MicroSystems, Inc.Sanken and Allegro reserve the right to make, from time to time, such de p ar t ures from the detail spec i f i c a t ions as may be re q uired to per m it im-p rove m ents in the per f or m ance, reliability, or manufacturability of its prod u cts.

BP1808以固定频率400KHz模式工作。通过采集接在CS引脚和VOUT引脚 之间采样电阻上的电压（V-），与内部基准0.2V（V+）比较，通过误差放 大器（EA），控制Comp的电压（ V+ ），Comp电压与内部振荡产生的固定 锯齿波（V-）比较，来决定导通时间。当输出电流减小时，采样电阻上的 电压小于0.2V，通过EA把Comp电压拉高，导通时间增大，从而使采样电阻 上的电压维持在0.2V，输出电流维持设定值，反之亦然。

设计注意事项 BOOST应用电感选取计算方法
先计算系统工作在零界模式下的电感量：
L
(Vo-Vin) *Vin2 2*Vo2 * Io*f
一般选取以上计算得到的感量的2~4倍。电感选的太小，会使峰值 电流变大，流过MOS和二极管的有效值变大，加大了导通损耗。但是 电感太大，首先，在相同尺寸下感量越大，饱和电流会越小；其次， 感量越大所需的铜线匝数增加，阻抗增加，损耗也增加；最后，加大 电感量会使环路的响应时间变慢。

system clock must be supplied on SCKI (pin 6).The PCM1808has a system clock detection circuit which automatically senses if the system clock is operating at 256f S ,384f S ,or 512f S in slave mode.In master mode,the system clock frequency must be controlled through the serial control port,which uses MD1(pin 111)and MD0(pin 10).The system clock is divided down automatically to generate frequencies of 128f S and 64f S ,which are used to operate the digital filter and the delta-sigma modulator,respectively.Table 1shows some typical relationships between sampling frequency and system clock frequency,and Figure 17shows system clock timing.Table 1.Sampling Frequency and System Clock FrequencySAMPLING FREQUENCY (kHz)SYSTEM CLOCK FREQUENCY (f SCLK )(MHz)256f S384f S 512f S 8 2.048 3.072

avoid pop noise,and the functions come into operation in some cases as described in several following sections.The level changes from 0dB to mute or mute to 0dB are performed using calculated pseudo S-shaped characteristics with zero-cross detection.Because of the zero-cross detection,the time needed for the fade in and fade out depends on the analog input frequency (f in ).It takes 48/f in until processing is completed.If there is no zero cross during 8192/f S ,DOUT is faded in or out by force during 48/f S (TIME OUT).Figure 18illustrates the fade-in and fade-out operation processing.11Submit

OperationsThe PCM1808has an internal power-on-reset circuit,and initialization (reset)is performed automatically when the power supply (V DD )exceeds 2.2V (typical).While V DD <2.2V (typical),and for

PCM1808does not require a specific phase relationship between LRCK and SCKI,but does require the synchronization of LRCK and SCKI.If the relationship between LRCK and SCKI changes more than ±6BCKs for 64BCK/frame (±5BCKs for 48BCK/frame)during one sample period due to LRCK or SCKI jitter,internal operation of the ADC halts within 1/f S and digital output is forced to zero data (BPZ code)until resynchronization between LRCK and SCKI is established.In the case of changes less than ±5BCKs for 64BCK/frame (±4BCKs for 48BCK/frame),resynchronization does not occur and the previously described digital output control and discontinuity do not occur.Figure 25illustrates the digital output response for loss of synchronization and resynchronization.During data,the PCM1808can generate some noise in the audio signal.Also,the transition of normal data to undefined data creates a discontinuity in the digital output data,which can generate some noise in the audio signal.The digital output is valid after resynchronization completes and the time of 32/f S has elapsed.Because the fade-in operation is performed,it takes additional time of 48/f in or 48/f S until the level corresponding to the analog input signal is obtained.If synchronization is lost during the fade-in or fade-out operation,the operation stops and DOUT (pin 9)is forced to zero data immediately.The fade-in operation resumes

2006–REVISED AUGUST 2006APPLICATION INFORMATION (continued)To ensure low source impedance of the ADC references,0.1-µF ceramic and 10-µF electrolytic capacitors are recommended between V REF and AGND.These capacitors should be located as close as possible to the V REF pin to reduce dynamic errors on the ADC references.The DOUT pin has a large load-drive capability,but if the DOUT line is long,locating a buffer near the PCM1808and minimizing load capacitance is recommended to minimize the digital-analog crosstalk and maximize the dynamic performance of the ADC.The quality of the system clock can influence dynamic performance,as the PCM1808operates based on a system clock.Therefore,it may be necessary to consider the system clock duty,jitter,and the time difference between system

PB180828-156© 2018 Parker Hannifin Corporation Parker Hannifin CorporationIndustrial Gas Filtration and Generation Division 11501 Outlook Street, Suite 100 There are typically two basic problems with pulse valves: they won’t open, or they won’t close. The problem may be the valve housing is visibly cracked or broken, but frequently the cause is less obvious, and may not be within the valve itself.It is important to evaluate the entire pulsing system, from the air supply to the solenoid valve, and the timer.Problem:Valve will not openPotential Causes:• No power to timer or solenoids, or faulty steps in the timer • S olenoid coil continuity• B uildup of debris (oil, dirt, etc.) in solenoid plunger sleeve • T ubing between solenoid and pulse valve blocked• T ubing interior diameter less than 0.160 in. (4mm) or tubing length greater than 8 ft. (2.4 m)• Solenoid plunger worn • Holes in diaphragm • Blocked exhaust portsProblem:Valve will not close (leaks air)Potential Causes:• Solenoid leaks air• L eaks in tubing between solenoid and pulse valve • S olenoid continuously energized • Insufficent air supply• B locked bleedports in pulse valve housing • Bad seal at primary diaphragm seat • Broken diaphragm springsRecommendations:When troubleshooting any process equipment, it is important to follow all applicable safety procedures.Air Supply:At startup, and especially when new, quick pressurization is needed to fully seal and equalize pres s ure in the valve for proper operation. This type of valve uses equalized air pressures on un e qual surface areas to create the sealing force. If the back side pressure doesn’t equalize, the valve will not seal.This can be accomplished one of two ways. If only one or two valves don’t fully seal, try plugging the 3/8” side exhaust port to reduce leak a ge and let the valve reach pressure. If several or all valves are leak i ng, isolate the header from the air supply until the supply line is at full pres s ure, then quickly allow the header and valves to repressurize.If this problem occurs regularly, a ball valve may be installed at the header to ease isolation. Keep the valve closed until the supply line is up to full pressure, then open the valve to quickly pressurize the header and valves. The importance of this procedure increases with the number of valves in a system. If the problem persists, verify that the compressor, supply lines, and header are properly sized.Blocked Bleedports:Each valve has bleedports to allow air passage between both sides of the diaphragm to equalize pressure within the valve. Air pressure on the diaphragm’s larger top-side surface area and the supplemental spring force pushes the diaphragm into the closed position. If the bleedport is blocked, pressures won’t equalize. The spring’s force alone cannot shut the valve, so it remains open.PB180828-156© 2018 Parker Hannifin Corporation Parker Hannifin CorporationIndustrial Gas Filtration and Generation Division 11501 Outlook Street, Suite 100 Blockage-causing contaminant can come from a variety of places: the air itself, flaking rust or gal v a n i z a t ion from inside pipes, or shavings from threaded fittings. The easiest solution to this problem is to lightly tap the valve housing near the bleedport (with air header pressure maintained) to try to dislodge the contamination. This may cause the valve to shut. If the valve is still open, the next step depends on whether you have a single or double diaphragm.Single-Diaphragm ValvesThe only other option for a single-diaphragm valve is to take apart the valve and manually remove the blockage. (NOTE: The diagrams at right are generic. Always follow instructions in the operation manual for the particular valve.)Double-Diaphragm ValvesBecause double-diaphragm valves have two bleedports, there are two possible blockage points. Blockage at the large diaphragm will result in leakage out the blowpipe and probably will require valve disassembly. Blockage at the smaller diaphragm results in leakage out the side exhaust port. Try plugging this port (usually requires a 3/8” NPT plug), allowing header to reach full operating pressure, and then removing the plug. The valve should be shut. If this fails, disassembly of the valve is required. (NOTE: Always follow instructions provided in the operation manual for the particular valve.)DisassemblyTurn off the air supply to the header and bleed pressure from it. Remove the back from the valve. If the leak is out the 3/8” exhaust port on a double-diaphragm valve, start with the small diaphragm. A pipe cleaner or other flexible item may be used to clear each bleedport.Check the disk in the center of the large diaphragm for nicks or embedded material which would prevent sealing. An even groove in the disk is evidence that it is seating properly. Replace the diaphragm if the disk is the source of leakage. Also check the valve seat to assure a smooth flat surface without nicks or protrusions which would prevent an airtight seal. Following instructions in theoperation manual, reassemble the valve and try again.Double-Diaphragm ValveSingle-Diaphragm Valve。
