VFJA430 Jitter Attenuator with 3 Input Frequency Selections plus Free Run Mode RoHS Status Features ¾ ¾ ¾ ¾ Free Run Mode 8 KHz to 200 MHz Input Frequency Range Ultra Low Jitter and Phase Noise: -152 dBc/Hz @ 100KHz Low Power: < 150mW typical Applications ¾ ¾ Synchronous Ethernet Wireless Infrastructure Description The VFJA430 is a Jitter Attenuator that provides two LVCMOS outputs at the specified frequency. Two select inputs [S1,S0] allow the user to select 1 of 3 preset input frequencies or Free Run Mode. In Free Run mode the device outputs the nominal frequency and is not locked to the input reference frequency. Operating with a +3.3 volt power supply the device typically consumes 150 mW. The VFJA430 is available in a 19.5mm x 15.5 mm surface mount package.
