LOW SKEW 2 INPUT MUX AND 1 TO 8 CLOCK BUFFER CLOCK MUX AND BUFFER IDT™ / ICS™ LOW SKEW 2 INPUT MUX AND 1 TO 8 CLOCK BUFFER 2 ICS552-02 REV K 092309 Pin Assignment Input Source Select Pin Descriptions External Components A minimum number of external components are required for proper operation. Decoupling capacitors of 0.01 µ F should be connected between VDD on pin 2 and GND on pin 7, and between VDD on pin 15 and GND on pin 10, as close to the device as possible. A 33 Ω series terminating resistor should be used on each clock output if the trace is longer than 1 inch. To achieve the low output skews that the ICS552-02 is capable of, careful attention must be paid to board layout. Essentially, all 8 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 33 Ω on the others) will cause at least 15ps of skew. OE VDD VDD Q3 Q4 INA GND GND INB SELA

These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
