CMOS TCXO

TKD CMOS TCXO oscillators integrate temperature compensation with full-swing CMOS output, delivering stable clocks that drive digital logic directly. In compact 2016–3225 packages with ±2.5 ppm class stability, they suit GNSS receivers, wireless modules and industrial control.

Ranges of CMOS TCXO

These temperature-compensated oscillators provide rail-to-rail CMOS output for direct connection to processors, RF transceivers and logic ICs. Compact ceramic packages, tight stability and low power consumption make them a straightforward choice for wireless and industrial timing.

CMOS Output Characteristics in TCXO Clock Design

Full-swing output

CMOS TCXO delivers rail-to-rail levels that drive standard digital inputs directly, eliminating the coupling and level-shifting circuits needed with clipped-sine outputs.

Drive capability

Outputs typically drive 10–15 pF loads with fast rise/fall times, so the clock can fan out to several digital loads with clean edges.

Current consumption

Full-swing CMOS switching draws more current than clipped-sine, so balance drive strength and load count to keep power within budget in battery devices.

Logic-Level Compatibility and PCB Design for CMOS TCXO

Voltage matching

Verify the TCXO supply and output swing match the receiving IC's logic levels; 1.8 V, 2.5 V and 3.3 V versions cover common MCU and SoC I/O voltages.

Output loading

Keep the total capacitive load at or below the rated value to preserve rise/fall times and avoid signal degradation on long traces.

PCB integration

Route the clock trace with a clean return path, place the TCXO close to the load, and decouple both VCC and the output node to reduce noise coupling.
