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

• Two differential HCSL output pairs at: 100MHz, 125MHz or

250MHz

• HCSL outputs can be terminated to drive LVDS loads up to

175MHz

• 25MHz crystal interface

• Supports the following output frequencies: 25MHz, 100MHz,

125MHz or 250MHz

• Supports SSC downspread, centerspread and no spread options

• Cycle-to-cycle jitter: 55ps (maximum)

• Period jitter, RMS: 4.15ps (maximum)

• Full 3.3V operating supply mode
