GENERAL DESCRIPTION
The 843011 is a Fibre Channel Clock Generator.
The 843011 uses a 26.5625MHz crystal to synthesize
106.25MHz or a 25MHz crystal to synthesize 100MHz. The
843011 has excellent <1ps phase jitter performance, over the
637kHz – 10MHz integration range. The 843011 is packaged
in a small 8-pin TSSOP, making it ideal for use in systems with
limited board space.
