Overview
Description
The 840024I is a four-output LVCMOS/LVTTL synthesizer optimized to generate Ethernet reference clock frequency. The 840024I uses Renesas' third generation of low phase noise VCO technology and can achieve 1ps or lower typical random RMS phase jitter, easily meeting Ethernet jitter requirements. The 840024I is packaged in a small 20-pin TSSOP package.
Features
- Four LVCMOS/LVTTL outputs
- Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended clock input
- Supports the following output frequency: 125MHz
- RMS phase jitter at 125MHz (1.875MHz to 20MHz): 0.6ps (typical)
- Power supply modes:
Core/Output
3.3V/3.3V
3.3V/2.5V
2.5V/2.5V - -40 °C to 85 °C ambient operating temperature
- Available in a lead-free (RoHS 6) package
