TSM22-H50CQ18ST-28.63636M

Oscillators Overview

The TSM22-H50CQ18ST-28.63636M is a standard crystal oscillator (XO) manufactured by Transko Electronics, Inc. It operates at a fixed frequency of 28.63636 MHz with an HCMOS output signal type. The device requires a 1.8V supply voltage and features an enable/disable function for power management. Frequency stability is rated at ±50ppm over the operating temperature range of -40°C to +85°C. The component is housed in a compact 4-SMD, No Lead package, suitable for surface mount applications.

Oscillators Feature Summary

• HCMOS output interface for digital logic compatibility
• Integrated enable/disable control functionality
• Standard crystal resonator technology
• Surface mount package design

Oscillators Applications

• Digital clock signal generation
• Microcontroller system timing
• Communication interface synchronization
• Embedded system reference clocks

Oscillators Procurement Notes

Verify the specific suffix codes against official Transko documentation to ensure correct voltage, frequency, and package variations. Confirm that the HCMOS output level matches the target circuit requirements. Check for any recent product lifecycle updates or discontinuation notices from the manufacturer before finalizing procurement plans.

Oscillators Selection Notes

Select this component when a precise 28.63636 MHz reference is required with low power consumption due to the 1.8V operation. Ensure the ±50ppm stability meets the system timing tolerance. Verify that the 4-SMD footprint fits the PCB layout constraints and that the enable pin can be controlled by the host processor.

Oscillators Part Context

This part belongs to the TSM22 series of MEMS-based oscillators from Transko Electronics. The series offers various frequencies and voltages. This specific model represents a standard XO variant with HCMOS output, distinct from TCXO or OCXO families which offer higher stability but different form factors and power profiles.

Oscillators Replacement Considerations

Transko suggests the TMM series as a potential drop-in replacement for certain legacy components, though direct substitution requires verification of electrical parameters. Cross-reference with other manufacturers' 28.63636 MHz HCMOS oscillators only if pinout and voltage compatibility are confirmed.
