DESCRIPTION
The PLL650-07 is a low cost, low jitter, high
performance clock synthesizer. With PhaseLink's
proprietary analog Phase Locked Loop techniques, this
device can produce multiple clock outputs from a 25.0MHz
crystal or reference clock. This makes the PLL650-07 an
excellent choice for systems requiring clocking for network
chips and ASICs.
