描述
The 843001CI is a Fibre Channel Clock Generator and a member of the family of high performance devices from IDT. The 843001CI uses either a 26.5625MHz or a 23.4375MHz crystal to synthesize 106.25MHz, 187.5MHz or 212.5MHz, using the FREQ_SEL pin. The 843001CI has excellent <1ps phase jitter performance, over the 637kHz – 10MHz integration range. The 843001CI is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
