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.
