VTX-T30-25MR10-20.000M-TR

Oscillators Overview

The VTX-T30-25MR10-20.000M-TR is a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by Transko Electronics, Inc. It operates at a nominal frequency of 20 MHz with CMOS output logic. The device requires a 3.3V supply voltage and features amplitude control functionality. It is housed in a compact 4-SMD, No Lead package with dimensions of 0.197 inches in length and 0.126 inches in width. The component supports an operating temperature range from -40°C to +85°C and draws a current of 8mA.

Oscillators Feature Summary

• Integrated voltage control for frequency tuning within the VCTCXO architecture
• Amplitude control capability for signal level management
• CMOS output interface compatible with standard digital logic circuits
• Wide industrial temperature rating suitable for harsh environments

Oscillators Applications

• Portable wireless communication devices requiring stable clock sources
• Mobile test equipment needing precise frequency references
• Beacon systems utilizing low power oscillators
• Rescue systems demanding reliable timing components

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency, package type, and tape/reel configuration. Confirm that the 3.3V supply requirement aligns with the target system design. Check for any recent discontinuation notices or alternative part recommendations from Transko Electronics, Inc., as oscillator series may undergo updates. Ensure the 8mA current consumption fits within the power budget constraints of the application.

Oscillators Selection Notes

Select this component when a voltage-controlled crystal oscillator with CMOS outputs is required for 20 MHz applications. The 4-SMD no-lead package offers space-saving benefits for dense PCB layouts. Consider the -40°C to +85°C operating range for industrial or outdoor deployments. The amplitude control feature provides flexibility in signal conditioning. Verify compatibility with existing voltage rails and control circuitry before finalizing the selection.

Oscillators Part Context

This VCTCXO belongs to Transko Electronics' broader oscillator portfolio, which includes MEMS-based TMM series and OCXO options. The company positions its products as drop-in replacements for discontinued lines from other manufacturers, such as Abracon's ASTX-09 series. The VTX-T30 series specifically targets applications requiring compact form factors and stable performance across varying temperatures.

Oscillators Replacement Considerations

Transko suggests the TX-T and TFC5 series as potential drop-in replacements for discontinued Abracon TCXO/VCTCXO models like the ASTX-09 and ASVTX-09. Users should verify pinout compatibility and electrical specifications before substituting these parts. Official confirmation from Transko Electronics is recommended to ensure fit, form, and function alignment.
