• Tuning voltage:
0 to 10 Volts
VTO-2150-SMA provides a
fundamental, low jitter source as
a key component for the data
re-timing in the transmitter
subsystem and clock and data
recovery in the receiver of the
40 Gb fiber optic systems.

filtered through a bandpass filter
prior to outputting the signal at
