FemtoClock® Crystal-to-3.3V LVPECL Clock Generator

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

Features

  • One differential 3.3V LVPECL output
  • Crystal oscillator interface designed for 23.4375MHz or 26.5625MHz, 18pF parallel resonant crystal
