GENERAL DESCRIPTION

The 843022I-48 is a Fibre Channel Clock Generator. The

843022I-48 uses a 25MHz crystal to synthesize 125MHz or

75MHz. The 843022I-48 has excellent phase jitter perform-ance,

over the 12kHz – 20MHz integration range. The 843022I-48

is packaged in a small 8-pin TSSOP, making it ideal for use in

systems with limited board space.

FEATURES
