Description  
The VFJA434 is a Jitter Attenuator capable of providing an output frequency up to 200 MHz. 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  
less than 150 mW. The VFJA434 is configured with four LVCMOS output ports. The device is available in a  
19.5mm x 15.5 mm surface mount package.
