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.
