General Description
CLK, nCLK pair can accept most standard differential input levels.
The PCLK, nPCLK pair can accept LVPECL, CML, or SSTL input
levels. The device is internally synchronized to eliminate runt
pulses on the outputs during asynchronous assertion/deassertion
of the OE pin. The ICS8534-01’s low output and part-to-part skew
characteristics make it ideal for workstation, server, and other high
performance clock distribution applications.

Features
Pin Assignment
Twenty-two differential LVPECL outputs
Selectable differential CLK/nCLK or LVPECL clock inputs can
accept the following differential input levels: LVDS, LVPECL,
LVHSTL
CLK/nCLK pair can accept the following differential input levels:
