General Description

The ICS844S0258-07 is an eight output synthesizer optimized to generate Gigabit and 10 Gigabit Ethernet clocks.

Using a 25MHz, 18pF parallel resonant crystal, the device will generate 125MHz clocks with mixed LVDS and LVCMOS/ LVTTL output levels.

ICS844S0258-07 uses IDT’s 3rd generation low phase noise VCO technology and can achieve <1ps typical RMS phase jitter, easily meeting Ethernet jitter requirements.

Key Features

Seven LVDS differential output at 125MHz One LVCMOS/LVTTL single-ended outputs at 125MHz.
Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input and PLL bypass from a single select pin.
Output enable signal for three LVDS outputs.
RMS phase jitter @ 125MHz, using a 25MHz crystal (1.857MHz - 20MHz): 0.278ps (typical.
