ICS841664I
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.
Key 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):
- 45ps (typical) @ 125MHz
- Full 3.3V power supply mode
- -40°C to 85°C ambient operating temperature
- Lead-free (RoHS 6) packaging
