LMK61xx Ultra-Low Jitter Oscillators

Texas Instruments LMK61xx Ultra-Low Jitter Oscillators are high-performance oscillators that generate a commonly used reference clock. Each device is pre-programmed in the factory to support any reference clock frequency; supported output formats are LVPECL up to 1GHz, LVDS up to 900MHz 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 device operates from a single 3.3V ± 5% supply. These devices are ideal high-performance replacements for crystal, SAW, or silicon-based oscillators.
