Overview
Description
The 843204I-01 is a 4 output LVPECL synthesizer optimized to generate Gigabit Ethernet and SONET reference clock frequencies. Using a 19.44MHz and 25MHz, 18pF parallel resonant crystal, 155.52MHz and 156.25MHz frequencies can be generated. The 843204I-01 uses our FemtoClock™ low phase noise VCO technology and can achieve 1ps or lower typical RMS phase jitter.
Features
- Four 3.3V LVPECL outputs
- Selectable crystal oscillator interface or clock inputs
- Supports the following output frequencies: 155.52MHz and 156.25MHz
- VCO range: 560MHz - 680MHz
- RMS phase jitter @ 155.52MHz, using a 19.44MHz crystal (12kHz - 13MHz): 0.6ps (typical)
- RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz - 20MHz): 0.7ps (typical)
- Full 3.3V supply mode
- -40°C to 85°C ambient operating temperature
- Available in lead-free (RoHS 6) package
