Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target platform's power rails. Ensure the enable/disable pin configuration matches the control logic available in the host circuit to utilize the power-saving feature effectively.

Oscillators Selection Notes

Select this component when a low-profile, 1.8V HCMOS oscillator is required for high-frequency applications. Consider the 2.0 x 1.6 mm package size for PCB layout constraints. Evaluate the need for enable/disable control versus continuous operation based on system power efficiency goals. Compare against other frequencies in the TSM21 series if different clock speeds are needed.

Oscillators Part Context

This part belongs to the TSM21 series of ultra-miniature SMD HCMOS oscillators from Transko Electronics. The series offers various frequencies ranging from 25 MHz to 125 MHz. The TSM21-H50CQ18ST variant specifically targets 50 MHz applications with 1.8V operation, fitting within the broader family of compact timing solutions for modern electronic devices.

Oscillators Replacement Considerations

Direct substitutes include other TSM21 series parts with matching package and voltage but different frequencies, such as TSM21-H50CQ18ST-25.000M-TR. Cross-reference with other manufacturers' 2.0x1.6mm 1.8V HCMOS oscillators only if electrical parameters like jitter and phase noise are verified to be equivalent.
