TSM21-H50CQ33ST-26.000M

Oscillators Overview

The TSM21-H50CQ33ST-26.000M is a standard crystal oscillator manufactured by Transko Electronics, Inc., operating at a fixed frequency of 26.000 MHz. It utilizes HCMOS output logic and requires a 3.3V supply voltage. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 x 0.9 mm. The unit supports an operating temperature range of -40°C to 85°C and maintains a frequency stability of ±50 ppm.

Oscillators Feature Summary

• Ultra-miniature surface-mount design suitable for space-constrained PCB layouts
• Integrated enable/disable pin for active power control
• HCMOS output interface compatible with standard digital logic levels

Oscillators Applications

• Portable wireless communication devices
• Mobile test equipment
• Beacon systems
• Rescue systems

Oscillators Procurement Notes

Verify the specific suffix codes against official Transko documentation to ensure correct voltage, frequency, and package configuration. Confirm that the enable/disable functionality aligns with system power sequencing requirements. Check for RoHS compliance status if required by project specifications. Ensure the supplier provides valid traceability documents. Validate the operating temperature range against environmental conditions.

Oscillators Selection Notes

Select this component when a low-profile, high-frequency clock source is needed for digital circuits. The 2.0x1.6mm footprint is ideal for miniaturized electronics. Consider the ±50 ppm stability requirement for timing accuracy. The 3.3V supply must match the target system voltage. Verify that the HCMOS output swing is compatible with downstream input thresholds.

Oscillators Part Context

This part belongs to the TSM21 series of ultra-miniature SMD HCMOS oscillators from Transko Electronics. The series covers frequencies from 1MHz to 137MHz with various supply voltages including 1.8V and 3.3V. These components are designed as drop-in replacements for discontinued models from other manufacturers, offering fit, form, and function compatibility in small SMD packages.

Oscillators Replacement Considerations

Transko suggests the TMM series as a potential alternative for MEMS-based applications requiring similar form factors. For specific discontinued Epson Toyocom VG-1201CA models, the TSMV series is offered as a direct replacement. Verify electrical parameters and pinout compatibility before substitution.
