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.
