Description

The ICS843011C is a Fibre Channel clock generator that uses a 26.5625MHz crystal to synthesize 106.25MHz or a 25MHz crystal to synthesize 100MHz. The ICS843011C has excellent <1ps phase jitter performance, over the 637kHz to 10MHz integration range. The device is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
