ICS845204 Product details

Description

The ICS845204 is a 4 output PCI Express clock ICS synthesizer optimized to generate low jitter PCI HiPerClockS™ Express™ reference clocks with or without spread spectrum modulation and is a member of the HiPerClockS™ family of high performance clock solutions from IDT.Spread type and amount can be configured via the SSC control pins.Using a 25MHz, 18pF parallel resonant crystal, the device will generate M-LVDS clocks at either 25MHz, 100MHz, 125MHz or 250MHz.The ICS845204 uses a low jitter VC

Features

Four differential spread spectrum clock outputs.
Each output can be individually disabled by separate output-enable inputs.
Crystal oscillator interface designed for 18pF, 25MHz parallel resonant crystal.
Supports the following output frequencies: 25MHz, 100MHz, 125MHz or 250MHz.
VCO range: 250MHz - 700MHz.
Supports SSC downspread at 0.05% and -0.75%, centerspread at ±0.25% and no spread options.
Cycle-to-cycle jitter: 50ps (maximum.
