2 / 10 page ICS621 LOW SKEW 1 TO 4 CLOCK BUFFER FAN OUT BUFFER IDT™ / ICS™ LOW SKEW 1 TO 4 CLOCK BUFFER 2 ICS621 REV B 030907 Pin Assignment (8-pin SOIC) Pin Assignment (8-pin DFN) Pin Descriptions External Components A minimum number of external components are required for proper operation. A decoupling capacitor of 0.01 µF should be connected between VDD on pin 7 and GND on pin 6, as close to the device as possible. A 33 Ω series terminating resistor may be used on each clock output if the trace is longer than 1 inch. To achieve the low output skew that the ICS621 is capable of, careful attention must be paid to board layout. Essentially, all four outputs must have identical terminations, identical loads and identical trace geometries. If they do not, the output skew will be degraded. For example, using a 30 Ω series termination on one output (with 33Ω on the others) will cause at least 15 ps of skew. 1 2 3 4 5 6 7 8 ICLK Q1 Q2 Q3 Q4 OE VDD GND 1 Q3 Q2 GND VDD Q1 Q4 ICLK OE 5 8 4 Pin Number Pin Name Pin Type Pin Description 1 ICLK Input Clock Input. 3.3 V tolerant input. 2 Q1 Output Clock Output 1. 3 Q2 Output Clock Output 2. 4 Q3 Output Clock Output 3. 5 Q4 Output Clock Output 4. 6 GND Power Connect to ground. 7 VDD Power Connect to +1.2 V or +1.8 V. 8 OE Input Output Enable.
