IDT8R43002I-01
Description
The IDT8R43002I-01 is a two output LVPECL synthesizer optimized to generate Ethernet reference clock frequencies. Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the two frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, and 62.5MHz.
Key Features
- Two 3.3V or 2.5V LVPECL outputs
- Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input
- Supports the following output frequencies: 156.25MHz, 125MHz and 62.5MHz
- VCO range: 560MHz - 680MHz
- RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz-20MHz): 0.55ps (typical)
- Output skew: 30ps (maximum)
- Supply Voltage Modes Core/Outputs 3.3/3.3 2.5/2.5
- -40°C to 85°C ambient operating temperature
- Available in lead-free RoHS-compliant packages TABLE
