FEATURES
DESCRIPTION
The PLL 650-06 is a low cost, low jitter, and high
performance clock synthesizer. Using PhaseLink’s
proprietary analog Phase Locked Loop techniques, this
device can produce one 50MHz output clock and one
selectable 75MHz or 66.6MHz output clock from a single
low cost 25.0MHz crystal. This makes the PLL650-06 ideal
for networking applications.
