TSM21-H50CQ33ST-20.000M

Oscillators Overview

The TSM21-H50CQ33ST-20.000M is a 20 MHz crystal oscillator (XO) manufactured by Transko Electronics, Inc. It features HCMOS output signals and operates on a 3.3V supply voltage. The device includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm. The component supports surface mount installation and is designed for standard operating temperature ranges.

Oscillators Feature Summary

• HCMOS output signal compatibility
• Integrated enable and disable control functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose timing circuits
• Embedded systems requiring stable clock sources
• Portable electronic devices

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and package variant matches the design requirements. Confirm RoHS3 compliance status if environmental regulations apply to the target assembly. Check moisture sensitivity level ratings prior to soldering processes to prevent damage during reflow. Ensure the supplier provides official documentation from Transko Electronics, Inc. rather than third-party summaries.

Oscillators Selection Notes

Select this component when a 20 MHz HCMOS clock source is required in a small form factor. The 3.3V supply voltage aligns with standard logic levels. The enable/disable feature allows for dynamic power control in battery-operated applications. Consider the 4-SMD package size constraints against board space limitations before finalizing the design.

Oscillators Part Context

This part belongs to the TSM series of oscillators from Transko Electronics, Inc., which utilizes MEMS technology for frequency generation. The series offers various frequencies and packages, ranging from 2.0x1.6mm to larger sizes. The TSM21 model specifically targets standard XO applications with HCMOS outputs.

Oscillators Replacement Considerations

Transko recommends the TSMV series as a drop-in replacement for discontinued Epson Toyocom VG-1201CA models. Verify pinout and electrical specifications match before substituting other manufacturers' parts.
