FemtoClock Crystal-to-3.3V LVPECL Frequency

Synthesizer

8V43042

Datasheet

General Description

Features

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 3^rdgeneration 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.

• Two 3.3V differential LVPECL output pairs

• Selectable crystal oscillator interface or LVCMOS/LVTTL

single-ended clock input

• Supports the following output frequencies: 156.25MHz, 150MHz

• RMS phase jitter @ 156.25MHz, using a 25MHz crystal

(1.875MHz – 20MHz): 0.437ps (typical)

• Full 3.3V supply modes

• 0°C to 70°C ambient operating temperature

• Lead-free (RoHS 6) packaging
