CDC6CE025000-Q1 (BAW Oscillator)

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

The CDC6x device is an ultra-low jitter, fixed-frequency oscillator which incorporates the BAW as the resonator source. The device is factory-programmed per specific operation mode, including frequency, voltage, output type, and function pin. With a high-performance fractional frequency divider, the CDC6x is capable of producing any frequency within the specified range providing a single device family for all frequency needs.

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.
