844N255I Overview
Description
The 844N255I is a 6-output clock synthesizer designed for wireless infrastructure clock applications. The device uses IDT’s fourth generation FemtoClock® NG technology for an optimum of high clock frequency and low phase noise performance, combined with a low power consumption and high power supply noise rejection.
Key Features
- 4TH generation FemtoClock® NG technology
- Selectable 156.25MHz, 125MHz, 100MHz, 50MHz and 25MHz output clock signals synthesized from a 25MHz reference frequency
- Six differential LVDS clock outputs
- Crystal interface designed for a 25MHz crystal
- RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1MHz
- 20MHz): 0.27ps (typical)
- Internal regulator for optimum noise rejection
- LVCMOS interface levels for the frequency select and output enable inputs
- Full 2.5V supply voltage
- Lead-free (RoHS
