The ICS508 is the most cost effective way to
generate a high quality, high frequency CMOS
clock output from a PECL clock input.
The ICS508 has separate VDD supplies for the
PECL input buffer and the output buffer allowing
different voltages to be used. For example, the
input clock could use a 3.3 V supply while the
output operates from 2.5 V.
The device has an Output Enable pin that tri-states
the clock output when the OE pin is taken low.
The ICS508 is a member of the ClockBlocks™
family of devices.
