Key Features
- Multioutput Clock Distribution: Provides 12 LVDS outputs in four groups, with the ability to reconfigure any of the 800 MHz LVDS outputs as two 250 MHz CMOS outputs.
- On-Chip PLL and VCO: The VCO tunes from 2.27 GHz to 2.65 GHz, and an external 3.3 V/5 V VCO/VCXO of up to 2.4 GHz can also be used.
- Serial Interface: Supports both SPI and I²C ports for flexible configuration and control.
- EEPROM: In-package EEPROM for storing user-defined register settings for power-up and chip reset.
- Divider and Phase Control: Each output group has a divider that allows setting both the divide ratio (from 1 to 32) and the phase (coarse delay).
- Low Jitter Performance: Subpicosecond jitter performance, making it suitable for high-speed applications requiring precise clock signals.
Applications
- Clock Distribution and Generation: For SONET, 10Ge, 10G FC, and other 10 Gbps protocols.
