FEMTOCLOCKS LVCMOS/CRYSTAL-TOSSTL_2 FREQUENCY SYNTHESIZER ICS848004I The ICS848004I is a 4 output SSTL_2 Synthesizer optimized to generate Fibre Channel reference clock HiPerClockS frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from IDT. Using a 26.5625MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 fre- quency select pins F_SEL[1:0] 212.5MHz, 187.5MHz, 159.375MHz, 156.25MHz, 106.25MHz and 53.125MHz. The ICS848004I uses IDT’s 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Fibre Channel jitter requirements. The ICS848004I is packaged in a small 24-pin TSSOP package.

FEMTOCLOCKS LVCMOS/CRYSTAL-TOSSTL_2 FREQUENCY SYNTHESIZER

ICS848004I

The ICS848004I is a 4 output SSTL_2 Synthesizer
optimized to generate Fibre Channel reference clock

HiPerClockS frequencies and is a member of the HiPerClocksTM
family of high performance clock solutions from IDT.

Using a 26.5625MHz 18pF parallel resonant crystal,
the following frequencies can be generated based on the 2 fre-
quency select pins F_SEL[1:0] 212.5MHz, 187.5MHz,
159.375MHz, 156.25MHz, 106.25MHz and 53.125MHz. The

ICS848004I uses IDT’s 3rd generation low phase noise VCO
technology and can achieve 1ps or lower typical rms phase jitter,
easily meeting Fibre Channel jitter requirements. The ICS848004I
is packaged in a small 24-pin TSSOP package.
