Texas Instruments LMK60xx Fixed Frequency Differential Oscillators

Texas Instruments LMK60xx Fixed Frequency Differential Oscillators are low jitter oscillator that generates a commonly used reference clock. The device is pre-programmed in the factory to support any reference clock frequency. The supported output formats are LVPECL, LVDS up to 800MHz, and HCSL up to 400MHz. Internal power conditioning provides excellent power supply ripple rejection (PSRR), reducing the cost and complexity of the power delivery network. The Texas Instruments LMK60xx operates from a single 3.3V ±5% supply.
