Description

The 840011 is a Fibre Channel Clock Generator and a member of the family of high performance devices from IDT. The 840011 uses a 26.5625MHz or 25MHz crystal to synthesize 106.25MHz or 100MHz respectively. The 840011 has excellent phase jitter performance, from 637kHz – 10MHz integration range. The 840011 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
