Texas Instruments LMK61PD0A2 Low Jitter Differential Oscillators
Texas Instruments LMK61PD0A2 Ultra Low-Jitter Differential Oscillators are a PLLatinum™ pin selectable oscillator that generates commonly used reference clocks. The device is pre-programmed in the factory to support seven unique reference clock frequencies that can be selected by pin-strapping each of FS[1:0] to VDD, GND, or NC (no connect). The output format is selected between LVPECL, LVDS, or HCSL by pin-strapping OS to VDD, GND, or NC. 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.
