LMK61XX High-Performance Ultra-Low Jitter Oscillator

1 Features

3 Description

The LMK61XX is an ultra-low jitter oscillator that

1

Ultra-low Noise, High Performance

generates a commonly used reference clock. The

–

Jitter: 90 fs RMS typical Fout > 100 MHz

device is pre-programmed in factory to support any

–

PSRR: -70 dBc, robust supply noise immunity

reference clock frequency; supported output formats

are LVPECL up to 1 GHz, LVDS up to 900 MHz, and

•

Supported Output Format

HCSL up to 400 MHz. Internal power conditioning
