TSM75-H20CQ33ST-51.840M

Oscillators Overview

The TSM75-H20CQ33ST-51.840M is a miniature ceramic surface-mount crystal oscillator manufactured by Transko Electronics, Inc. It operates at a nominal frequency of 51.84 MHz with a stability of ±10 ppm. The device utilizes HCMOS output logic and requires a 3.3V supply voltage. It features an enable/disable control function for power management. The component is housed in a compact 4-SMD, No Lead package with dimensions of 7.0 mm x 5.0 mm x 1.5 mm, designed for high-density circuit board applications.

Oscillators Feature Summary

• Miniature ceramic SMD construction for space-constrained designs
• HCMOS output interface compatible with standard digital logic
• Integrated enable/disable functionality for power optimization
• High frequency stability suitable for precision timing requirements

Oscillators Applications

• High-precision timing applications requiring stable clock signals
• Digital communication systems needing reliable clock sources
• Embedded systems with limited board space constraints

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and package variant matches the design requirements. Confirm that the HCMOS output level aligns with the target system's input voltage thresholds. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the enable pin configuration supports the intended power management strategy during procurement planning.

Oscillators Selection Notes

Select this component when a 51.84 MHz clock signal is required with ±10 ppm stability. Consider the 3.3V operating voltage and HCMOS output characteristics for compatibility. Evaluate the 7.0x5.0mm footprint against available PCB real estate. The enable feature makes it suitable for battery-powered or power-sensitive designs compared to always-on oscillators.

Oscillators Part Context

This part belongs to the TSM75 series of miniature ceramic SMD oscillators from Transko Electronics. The series emphasizes low cost and short lead times while maintaining performance. These oscillators are designed as drop-in replacements for larger through-hole or standard SMD packages, offering similar electrical characteristics in a significantly reduced physical profile for modern electronics.

Oscillators Replacement Considerations

Direct substitutes within the same series include other TSM75 variants with different frequencies or supply voltages, such as TSM75-H20CQ33ST-76.800M. Verify pinout compatibility and electrical specifications before substitution. Cross-reference with manufacturer datasheets to confirm mechanical and thermal equivalence.
