DATASHEET 3.3 VOLT ZERO DELAY, LOW SKEW BUFFER ICS671-03 IDT™ 3.3 VOLT ZERO DELAY, LOW SKEW BUFFER 1 ICS671-03 REV C 110409 Description The ICS671-03 is a low phase noise, high speed PLL based, 8 output, low skew zero delay buffer. Based on IDT’s proprietary low jitter Phase Locked Loop (PLL) techniques, the device provides eight low skew outputs at speeds up to 133 MHz at 3.3 V. The outputs can be generated from the PLL (for zero delay), or directly from the input (for testing), and can be set to tri-state mode or to stop at a low level. For normal operation as a zero delay buffer, any output clock is tied to the FBIN pin. Features • Packaged in 16 pin narrow (150 mil) SOIC • Clock outputs from 10 to 133 MHz • Zero input-output delay • Eight low-skew (<200 ps) outputs • Device-to-device skew <700 ps • Low jitter (<200 ps) • Full CMOS outputs with 25 mA output drive capability at TTL levels • 5 V tolerant FBIN and CLKIN pins • Tri-state mode for board-level testing • Advanced, low power, sub-micron CMOS process • 3.3 V operating voltage • Industrial temperature range of -40 to 85 °C • Available in RoHS compliant (Pb free) package NOTE: EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 Block Diagram

ICS671-03 3.3 VOLT ZERO DELAY, LOW SKEW BUFFER ZDB AND MULTIPLIER IDT™ 3.3 VOLT ZERO DELAY, LOW SKEW BUFFER 3 ICS671-03 REV C 110409 External Components The ICS671-03 requires a minimum number of external components for proper operation. Decoupling capacitors of 0.01µF should be connected between VDD and GND on pins 4 and 5, and VDD and GND on pins 13 and 12, as close to the device as possible. A series termination resistor of 33 Ω may be used close to each clock output pin to reduce reflections. Decoupling Capacitor A decoupling capacitor of 0.01µF must be connected between VDD and GND, as close to these pins as possible. For optimum device performance, the decoupling capacitor should be mounted on the component side of the PCB. Avoid the use of vias in the decoupling circuit. Series Termination Resistor When the PCB trace between the clock outputs and the loads are over 1 inch, series termination should be used. To series terminate a 50Ω trace (a commonly used trace impedance) place a 33Ω resistor in series with the clock line, as close to the clock output pin as possible. The nominal impedance of the clock output is 20Ω. PCB Layout Recommendations For optimum device performance and lowest output phase noise, the following guidelines should be observed. 1) The 0.01µF decoupling capacitor should be mounted on the component side of the board as close to the VDD pin as possible. No vias should be used between decoupling capacitor and VDD pin. The PCB trace to VDD pin should be kept as short as possible, as should the PCB trace to the ground via. 2) The external crystal should be mounted just next to the device with short traces. The X1 and X2 traces should not be routed next to each other with minimum spaces, instead they should be separated and away from other traces. 3) To minimize EMI, the 33Ω series termination resistor (if needed) should be placed close to the clock output. 4) An optimum layout is one with all components on the same side of the board, minimizing vias through other signal layers. Other signal traces should be routed away from the ICS671-03. This includes signal traces just underneath the device, or on layers adjacent to the ground plane layer used by the device.
