FEMTOCLOCKS CRYSTAL-TO-LVPECL 350MHZ FREQUENCY MARGINING SYNTHESIZER

ICS843207-350

The ICS843207-350 is a low phase-noise
frequency margining synthesizer that targets

HiPerClockS clocking for high perfor mance interfaces such
as SPI4.2 and is a member of the HiPerClockS
family of high performance clock solutions from

IDT. In the default mode, each output can be configured
individually to generate an 87.5MHz, 175MHZ or 350MHz

LVPECL output clock signal from a 14MHz crystal input.

There is also a frequency margining mode available where
the device can be configured, using control pins, to vary
the output frequency up or down from nominal by The

ICS843207-350 is provided in a 48-pin LQFP package.
