Description

The VFJA400 is a Jitter Attenuator capable of providing an output frequency up to 200MHz. Two select inputs

[S1,S0] allow the user to select 1 of 4 preset input frequencies. A Lock Detect signal indicates when the output

signal is frequency locked to the input. Operating with a +3.3 volt power supply the device typically consumes

150mW. The output is configured as a differential LVPECL signal and requires external termination resistors.

The VFJA400 is available in a 19.5mm x 15.5mm surface mount package.
