General Description

The 8V43042 is a two output LVPECL synthesizer optimized to

generate low jitter reference clock sources. Using a 25MHz or

24MHz, 12pF parallel resonant crystal, it can generate 156.25MHz

or 150MHz, The 8V43042 uses 8V43042’s 3rd generation low phase

noise VCO technology and can achieve 1ps or lower typical RMS

phase jitter, easily meeting Ethernet jitter requirements. The

8V43042 is packaged in a small 20-pin TSSOP package.

Features
