Description
The VFJA907 is a Jitter Attenuator that provides 4 LVCMOS outputs with a frequency of 161.1328 MHz. A Lock
Detect signal indicates when the device is in “lock”. Operating with a +3.3 volt power supply the device typically
consumes 150 mW. The VFJA907 is available in a 19.5mm x 15.5 mm surface mount package.
