ICS844004I-01 Overview
Description
The ICS844004I-01 is a 4 output LVDS Synthesizer optimized to generate Ethernet reference clock HiPerClockS™ frequencies and is a member of the HiPerClocks TM family of high performance clock solutions from ICS. Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz and 62.5MHz.
Key Features
- Four LVDS outputs
- Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input
- Supports the following output frequencies: 156.25MHz, 125MHz, 62.5MHz
- VCO range: 560MHz
- RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz
- 20MHz): 0.41ps (typical)
- Full 3.3V or 2.5V supply modes
- 40°C to 85°C ambient operating temperature
