3 Description

The LMK60XX device is a 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, and LVDS up to 800 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.
