Description

The ICS650-27 is a low cost, low jitter, high performance clock synthesizer for networking applications. Using analog Phase-Locked Loop (PLL) techniques, the device accepts a 12.5 MHz or 25 MHz clock or fundamental mode crystal input to produce multiple output clocks for networking chips, PCI devices, SDRAM, and ASICs. The ICS650-27 outputs all have zero ppm synthesis error. The ICS650-27 is pin compatible and functionally equivalent to the ICS650-07.

It is a performance upgrade and is recommended for all new 3.3V designs. See the MK74CB214, ICS551, and ICS552-01 for non-PLL buffer devices which produce multiple low-skew copies of these output clocks. See the ICS570, ICS9112-16/17/18 for zero delay buffers that can synchronize outputs and other needed clocks.
