Texas Instruments' LMK61xx are ultra-low-jitter oscillators that generate a commonly used reference clock. These devices are 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 provides excellent power supply ripple rejection (PSRR), reducing the cost and complexity of the power delivery network. These devices operate from a single 3.3 V ±5% supply.
