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.
