LMK61E2 - Texas Instruments

LMK61E2 Ultra-Low Jitter Programmable Oscillator

The LMK61E2 device is an ultra-low jitter PLLatinum™ programmable oscillator with a fractional-N frequency synthesizer with integrated VCO that generates commonly used reference clocks. The outputs can be configured as LVPECL, LVDS, or HCSL. The device features self start-up from on-chip EEPROM that is factory programmed to generate 156.25-MHz LVPECL output..
