General 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. The device has excellent phase
jitter (<1ps RMS) suitable to clock components requiring precise and
low-jitter sRIO clock signals. Designed for telecom, networking and
industrial application, the ICS841664I can also drive the high-speed
sRIO SerDes clock inputs of communication processors, DSPs,
switches and bridges.
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, using a 25MHz crystal (1.875MHz - 20MHz):
0.45ps (typical) @ 125MHz
Full 3.3V power supply mode
-40°C to 85°C ambient operating temperature
