General Description

The ICS844011 is a Fibre Channel Clock Generator. The

ICS844011 uses an 18pF parallel resonant crystal. For Fibre

Channel applications, a 26.5625MHz crystal is used. The

ICS844011 has excellent <1ps phase jitter performance, over the

637kHz - 10MHz integration range. The ICS844011 is packaged in a

small 8-pin TSSOP, making it ideal for use in systems with limited

board space.
