3 Description

The LMK60EX is a family of low jitter oscillators that

generate a commonly used reference clock. The

device is pre-programmed in factory to support any

reference clock frequency; supported output formats

are LVPECL, LVDS, 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.
