Texas Instruments’ Bulk-Acoustic Wave (BAW) is a micro-resonator technology that enables the integration of high-precision and ultra-low jitter clocks directly into packages that contain other circuits. BAW is fully designed and manufactured at TI factories like other silicon-based fabrication processes.

The LMK6x device is a low jitter, fixed-frequency oscillator which incorporates the BAW as the resonator source. With a high-performance fractional frequency divider, the LMK6x is capable of producing any frequency within the specified range providing a single device family for all frequency needs. The device is factory-programmed per specific operation mode, including frequency, voltage, output type, and function pin. Contact a TI representative for additional frequencies or other options.

The high-performance clocking, mechanical stability, flexibility and small package options for this device are designed for reference and core clocks in high-speed SERDES used in Telecommunications, Data and Enterprise Network and Industrial applications.
