VFJA400 Quad Input to 200MHz Jitter Attenuator w/ FOUT to 200MHz RoHS Status Features ¾ ¾ ¾ ¾ 10MHz to 200MHz Output Frequency Range 8KHz to 200MHz Input Frequency Range Ultra Low Jitter and Phase Noise: -130 dBc/Hz @ 1KHz Low Power: < 150mW typical Applications ¾ ¾ ¾ Sonet / SDH / ATM 10 Gigabit Ethernet Wireless Infrastructure 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.
