FEMTOCLOCKS CRYSTAL-TO3.3V LVPECL FREQUENCY SYNTHESIZER

ICS843206I

The ICS843206I is a 6 output LVPECL Synthesizer
optimized to generate Gigabit Ethernet and SONET

HiPerClockS reference clock frequencies and is a member of the

HiPerClocksTM family of high performance clock
solutions from IDT. Using a 19.44MHz and 25MHz,
18pF parallel resonant crystal, 155.52MHz and 156.25MHz
frequencies can be generated. The ICS843206I uses IDT’s

FemtoClockTM low phase noise VCO technology and can achieve
1ps or lower typical RMS phase jitter. The ICS843206I is pack-
aged in a 48-pin TSSOP package.
• Six 3.3V differential LVPECL output pairs
• Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input
• Supports the following output frequencies 155.52MHz and 156.25MHz
