ICS553
Pin Assignment
Pin Descriptions
External Components
A minimum number of external components are required for proper operation. A decoupling capacitor of
0.01
μ
F should be connected between VDD on pin 1 and GND on pin 4, as close to the device as possible.
A 33
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 ICS553 is capable of, careful attention must be paid to board
layout. Essentially, all 4 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
series termination
on one output (with 33
on the others) will cause at least 15ps of skew.
