TSM22-H50CQ18ST-40.000M

Oscillators Overview

The TSM22-H50CQ18ST-40.000M is a standard crystal oscillator (XO) manufactured by Transko Electronics, Inc., operating at a fixed frequency of 40.0000 MHz. It utilizes HCMOS output logic levels and functions on a single 1.8V supply voltage. The device features an enable/disable control pin for power management flexibility. It is housed in a compact 4-SMD, no-lead surface-mount package with dimensions of 0.098 inches in length and 0.079 inches in width. The component is RoHS compliant and lead-free.

Oscillators Feature Summary

• HCMOS output interface for digital compatibility
• Integrated enable/disable functionality for power optimization
• Compact surface-mount design suitable for space-constrained layouts

Oscillators Applications

• Embedded systems requiring precise clock timing
• Consumer electronics with low-power constraints
• Industrial control modules utilizing standard CMOS logic

Oscillators Procurement Notes

Verify the specific suffix codes against official Transko documentation to ensure correct frequency tolerance and package variant. Confirm RoHS compliance status through manufacturer certificates. Cross-reference the 4-SMD footprint dimensions with PCB layout guidelines to prevent assembly errors. Ensure supply voltage matches the 1.8V specification before integration.

Oscillators Selection Notes

Select this component when a stable 40 MHz reference is required for HCMOS-compatible circuits. The 1.8V operation makes it suitable for modern low-voltage digital environments. Consider the enable pin requirement if dynamic power saving is necessary. Verify that the SMD package size fits within the available board real estate compared to larger through-hole alternatives.

Oscillators Part Context

This model belongs to the TSM22 series of surface-mount oscillators from Transko Electronics. The series offers various frequencies while maintaining consistent electrical characteristics and form factors. The H50CQ18ST designation indicates specific packaging and voltage parameters unique to this product line, distinguishing it from other Transko oscillator families.

Oscillators Replacement Considerations

Direct substitutes include other TSM22 series variants with identical footprints but different frequencies, such as TSM22-H50CQ18ST-38.400M or TSM22-H50CQ18ST-68.000M. Ensure any replacement maintains the 1.8V supply and HCMOS output requirements.
