3 Description

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), reducing the cost and complexity of the

power delivery network. The device operates from a

single 3.3 V ± 5% supply.
