PRELIMINARY

FEMTOCLOCK™ CRYSTAL-TO-

LVPECL/LVDS/LVCMOS CLOCK GENERATOR

ICS843S2807

GENERAL DESCRIPTION

FEATURES

ICS843S2807 is a low phase noise Clock Generator

• Five banks of outputs:

ICS

HiPerClockS™

and is a member of the HiperClockS™family of high

performance clock solutions from IDT. The device

provides five banks of outputs and a reference clock.

The banks can be enabled by using a common output

Bank A: one single-ended (QA0) LVCMOS output at: 133MHz

and one (QA1/nQA1) LVPECL output at: 66.67MHz, 100MHz

and 125MHz

Bank B: two (QB0, QB1) LVCMOS outputs at: 50MHz

Bank C: one (QC0/nQC0) differential LVPECL output at: 87.5MHz

Bank D: one (QD0/nQD0) differential LVDS output at: 350MHz

One single-ended LVCMOS reference clock output at: 25MHz

enable pin. A 25MHz crystal is used to generate the 50MHz,

66.67MHz, 87.5MHz, 100MHz, 125MHz, 133MHz and 350MHz

frequencies.

• Crystal input frequency: 25MHz

• Maximum output frequency: 350MHz

PIN ASSIGNMENT

•

5ꢀ frequency margining

• Full 3.3V operating supply

• 0°C to 70°C ambient operating temperature
