VFJA434 Quad Input to 200 MHz Jitter Attenuator w/ FOUT to 200 MHz RoHS Status Features 10 MHz to 200MHz Output Frequency Range 8 KHz to 200 MHz Input Frequency Range Ultra Low Jitter and Phase Noise: -143 dBc/Hz @ 1KHz Low Power: < 150mW typical Applications Sonet / SDH / ATM Carrier Ethernet Synchronizers Wireless Infrastructure 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.
