General Description
The ICS841202-245 is a two output clock synthesizer optimized to
generate low jitter with or without spread spectrum modulation.
Spread type and amount can be configured via the SSC control pins.
Using a 25MHz, 12pF parallel resonant crystal, the device will
generate HCSL clocks at either 25MHz, 100MHz, 125MHz or
250MHz. The ICS841202-245 uses a low jitter VCO and is packaged
in a 32-pin VFQFN package.
Features
