LMK61E2-125M - Texas Instruments

LMK61E2-125M High-Performance Ultra-Low Jitter Oscillator

The LMK61XX is an ultra-low jitter oscillator that generates a commonly used reference clock. The device is pre-programmed in factory to support any reference clock frequency; supported output formats are LVPECL up to 1 GHz, LVDS up to 900 MHz, and HCSL up to 400 MHz. Internal power conditioning provide excellent power supply ripple rejection (PSRR), reducin.
