The ICS8524 is a low skew, 1-to-22 Differential-to-HSTL
Fanout Buffer . The ICS8524 has two selectable clock inputs.
The 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
ICS8524’s low output and part-to-part skew characteristics
make it ideal for workstation, server, and other high
performance clock distribution applications.
