Texas Instruments LMK6x Low Jitter High-Performance BAW Oscillators

Texas Instruments LMK6x Low Jitter High-Performance BAW Oscillators are ultra-low, fixed-frequency oscillators incorporating the BAW as the resonator source. The devices are factory-programmed per specific operation mode, including frequency, voltage, output type, and function pin. With a high-performance fractional frequency divider, the TI LMK6x can produce any frequency within the specified range providing a single device family for all frequency needs.

The Texas Instruments LMK6x high-performance clocking, mechanical stability, flexibility, and small package options are designed for reference and core clocks in high-speed SERDES in telecommunications, data and enterprise networks, and industrial applications.
