FemtoClock™ Crystal-to-3.3V LVPECL Clock Generator

The 843SDN is a Gigabit Ethernet Clock Generator and a member of the high performance devices from IDT. The 843SDN uses a 24MHz crystal to synthesize 120MHz. The 843SDN uses IDT's 3rd generation low phase noise VCO technology, and can achieve <1ps rms phase jitter performance over the 12kHz – 20MHz integration range. The 843SDN is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.

Features

  • 1 differential 3.3V LVPECL output
  • Crystal oscillator interface designed for 23.2MHz – 30MHz, 18pF parallel resonant crystal
  • Output frequency range: 116MHz – 150MHz
  • VCO range: 580MHz – 750MHz
  • Output duty cycle range: 47% – 53%
  • RMS phase jitter @ 120MHz, using a 24MHz crystal (12kHz – 20MHz): 0.81ps (typical)
  • Full 3.3V supply mode
  • 0°C to 70°C ambient operating temperature
  • Industrial temperature information available upon request
  • Available in lead-free (RoHS 6) package
