ICS557-01 Datasheet说明书

PCI-EXPRESS CLOCK SOURCEDescriptionThe ICS557-01 is a clock chip designed for use inPCI-Express Cards as a clock source. It provides a pair of differential outputs at 100 MHz in a small 8-pin SOIC package.Using IDT’s patented Phase-Locked Loop (PLL) techniques, the device takes a 25 MHz crystal input and produces HCSL (Host Clock Signal Level) differential outputs at 100 MHz clock frequency. LVDS signal levels can also be supported via an alternative termination scheme.Features•Supports PCI-Express TM HCSL Outputs0.7 V current mode differential pair •Supports LVDS Output Levels•Packaged in 8-pin SOIC•RoHS 5 (green ) or RoHS 6 (green and lead free) compliant packaging•Operating voltage of 3.3 V•Low power consumption•Input frequency of 25 MHz•Short term jitter 100 ps (peak-to-peak)•Output Enable via pin selection•Industrial temperature range availableBlock DiagramPin Assignment Pin DescriptionsPin NumberPinNamePinTypePin Description1OE Input Output Enable signal(H = outputs are enabled, L = outputs are disabled/tristated).Internal pull-up resistor.2X1Input Crystal or clock input. Connect to a 25 MHz crystal or single ended clock. 3X2XO Crystal Connection. Connect to a parallel mode crystal.Leave floating if clock input.4GND Power Connect to ground.5IREF Output A 475Ω precision resistor connected between this pin and groundestablishes the external reference current.6CLK Output HCSL differential complementary clock output.7CLK Output HCSL differential clock output.8VDD Power Connect to +3.3 V.Applications Information External ComponentsA minimum number of external components are required for proper operation.Decoupling CapacitorsDecoupling capacitors of 0.01 μF should be connected between VDD and the ground plane (pin 4) as close to the VDD pin as possible. Do not share ground vias between components. Route power from power source through the capacitor pad and then into IDT pin.CrystalA 25 MHz fundamental mode parallel resonant crystal with C L = 16 pF should be used. This crystal must have less than 300 ppm of error across temperature in order for theICS557-01 to meet PCI Express specifications.Crystal CapacitorsCrystal capacitors are connected from pins X1 to ground and X2 to ground to optimize the accuracy of the output frequency.C L= Crystal’s load capacitance in pFCrystal Capacitors (pF) = (C L- 8) * 2For example, for a crystal with a 16 pF load cap, each external crystal cap would be 16 pF. (16-8)*2=16.Current Source (Iref) Reference Resistor - R RIf board target trace impedance (Z) is 50Ω, then R R = 475Ω(1%), providing IREF of 2.32 mA. The output current (I OH) is equal to 6*IREF.Output TerminationThe PCI-Express differential clock outputs of the ICS557-01 are open source drivers and require an external series resistor and a resistor to ground. These resistor values and their allowable locations are shown in detail in thePCI-Express Layout Guidelines section.The ICS557-01can also be configured for LVDS compatible voltage levels. See the LVDS Compatible Layout Guidelines sectionGeneral PCB Layout RecommendationsFor optimum device performance and lowest output phase noise, the following guidelines should be observed.1. Each 0.01µF decoupling capacitor should be mounted on the component side of the board as close to the VDD pin as possible.2. No vias should be used between decoupling capacitor and VDD pin.3. The PCB trace to VDD pin should be kept as short as possible, as should the PCB trace to the ground via. Distance of the ferrite bead and bulk decoupling from the device is less critical.4. An optimum layout is one with all components on the same side of the board, minimizing vias through other signal layers (any ferrite beads and bulk decoupling capacitors can be mounted on the back). Other signal traces should be routed away from the ICS557-01.This includes signal traces just underneath the device, or on layers adjacent to the ground plane layer used by the device.PCI-Express Layout GuidelinesFigure 1: PCI-Express Device RoutingTypical PCI-Express (HCSL) WaveformLVDS Compatible Layout GuidelinesFigure: LVDS Device RoutingTypical LVDS WaveformAbsolute Maximum RatingsStresses above the ratings listed below can cause permanent damage to the ICS557-01.

RETRIGGERABLE MONOSTABLE MULTIVIBRATORSThese dc triggered multivibrators feature pulse width control by three meth-ods. The basic pulse width is programmed by selection of external resistance and capacitance values. The LS122 has an internal timing resistor that allows the circuits to be used with only an external capacitor. Once triggered, the ba-sic pulse width may be extended by retriggering the gated low-level-active (A)or high-level-active (B) inputs, or be reduced by use of the overriding clear.•Overriding Clear Terminates Output Pulse•Compensated for V CC and T emperature Variations•DC Triggered from Active-High or Active-Low Gated Logic Inputs •Retriggerable for Very Long Output Pulses, up to 100% Duty Cycle •Internal Timing Resistors on LS122SN54/74LS122 (TOP VIEW)(SEE NOTES 1 THRU 4)SN54/74LS123 (TOP VIEW)(SEE NOTES 1 THRU 4)NOTES:1.An external timing capacitor may be connected between C ext and R ext /C ext (positive).2.To use the internal timing resistor of the LS122, connect R int to V CC .3.For improved pulse width accuracy connect an external resistor between R ext /C ext and V CC with R int open-circuited.4.To obtain variable pulse widths, connect an external variable resistance between R int /C ext and V CC .R ext/CR ext/C ext 11ĂRext/2CLRC extNC Ċ NO INTERNAL CONNECTION.。
