ICS844S0258-07 Crystal/LVCMOS-toLVDS/LVCMOS Frequency Synthesizer

ICS844S0258-07 Crystal/LVCMOS-toLVDS/LVCMOS Frequency Synthesizer

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 no.

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.
