LOW SKEW 2 INPUT MUX AND 1 TO 8 CLOCK BUFFER
ICS552-02
Description
Features
The ICS552-02 is a low skew, single-input to eight-
output clock buffer. The device offers a dual input with
pin select for switching between two clock sources. It is
part of IDT’s ClockBlocksTM family. See the ICS553 for
a 1 to 4 low skew buffer. For more than 8 outputs see
the MK74CBxxx BuffaloTM series of clock drivers.

Input
Selects either INA or INB. Internal pull-up resistor.
External Components
A minimum number of external components are required for proper operation. Decoupling capacitors of
0.01 µF 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 Ωseries 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 30Ω series termination
on one output (with 33Ωon the others) will cause at least 15ps of skew.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS552-02. 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.
