ICS843S2807

PRELIMINARY FEMTOCLOCK™ CRYSTAL-TOLVPECL/LVDS/LVCMOS CLOCK GENERATOR ICS843S2807 GENERAL DESCRIPTION ICS843S2807 is a low phase noise Clock Generator ICS and is a member of the HiperClockS™ family of high HiPerClockS™ 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 enable pin. A 25MHz crystal is used to generate the 50MHz, 66.67MHz, 87.5MHz, 100MHz, 125MHz, 133MHz and 350MHz frequencies. FEATURES Five banks of outputs: 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 PIN ASSIGNMENT Crystal input frequency: 25MHz Maximum output frequency: 350MHz ±5% frequency mar...
