Networking Clock Source
The MPC926508 is a low cost, low jitter, high performance clock
synthesizer for networking applications. Using analog Phase-Locked
Loop (PLL) techniques, the device accepts an input to produce multi-
ple output clocks for networking chips, PCI devices, SDRAM, and
ASICs. The MPC926508 outputs all have 0 ppm synthesis error.
