TSM32-H50CQ18ST-27.000M

Oscillators Overview

The TSM32-H50CQ18ST-27.000M is a surface-mount crystal oscillator manufactured by Transko Electronics, Inc., operating at a nominal frequency of 27.000 MHz. It utilizes an HCMOS output type and functions as a standard XO (crystal oscillator). The device is powered by a 3.3V supply voltage with a maximum current consumption of 30mA. It features a frequency stability of ±50ppm and supports an enable/disable function for power management. The component operates within a temperature range of -40°C to +85°C and is housed in a compact 4-SMD, no-lead package measuring 3.20mm x 2.50mm.

Oscillators Feature Summary

• HCMOS digital output interface
• Enable/Disable control functionality
• Surface mount SMD packaging

Oscillators Applications

• Embedded systems requiring precise clocking
• Industrial control equipment
• Telecommunications infrastructure modules

Oscillators Procurement Notes

Verify the specific suffix codes against official Transko documentation to ensure compatibility with required voltage levels and output types. Confirm that the ±50ppm stability specification meets the system timing requirements. Ensure the -40°C to +85°C operating range aligns with the environmental conditions of the target application. Cross-reference the 4-SMD footprint dimensions during PCB layout verification.

Oscillators Selection Notes

Select this component when a 27MHz clock source with moderate stability is required for industrial or commercial environments. The HCMOS output is suitable for direct interfacing with digital logic circuits. Consider the 3.3V supply constraint and the enable feature for power-sensitive designs. Evaluate the ±50ppm tolerance against the total system jitter budget before finalizing the selection.

Oscillators Part Context

This part belongs to the TSM32 series of miniature surface-mount oscillators from Transko Electronics. The series offers various frequencies and stability options in a standardized small footprint. It serves as a drop-in replacement for discontinued models such as Epson VG-1201CA variants, providing fit, form, and functional equivalence for legacy designs transitioning to modern components.

Oscillators Replacement Considerations

Transko recommends the TSMV series as a drop-in replacement for discontinued Epson VG-1201CA models, noting fit, form, and function compatibility. Verify pinout and electrical specifications against the original design requirements before substitution.
