ICS841664I - Crystal-to-HCSL Clock Generator

Description

The ICS841664I is an optimized sRIO clock generator and a member of the family of high-performance clock solutions from IDT.

The device uses a 25MHz parallel crystal to generate 125MHz and 156.25MHz clock signals, replacing solution requiring multiple oscillator and fanout buffer solutions.

Features

• Four differential HCSL clock outputs: configurable for sRIO (125MHz or 156.25MHz) clock signals One REF_OUT LVCMOS/LVTTL clock output.
• Selectable crystal oscillator interface, 25MHz, 18pF parallel resonant crystal or LVCMOS/LVTTL single-ended reference clock input or LVCMOS/LVTTL single-ended input.
• Supports the following output frequencies: 125MHz or 156.25MHz.
• VCO: 625MHz.
• Supports PLL bypass and output enable functions.
• RMS phase jitter,.
