TSM22-H20CQ18ST-26.000M

Oscillators Overview

The TSM22-H20CQ18ST-26.000M is a surface-mount HCMOS crystal oscillator manufactured by Transko Electronics, Inc. It operates at a nominal frequency of 26.000 MHz with a supply voltage of 1.8V. The device features enable/disable functionality and offers a frequency stability of ±10ppm. Designed for operation within a temperature range of 0°C to +70°C, it draws a maximum current of 30mA. The component is housed in a compact 4-SMD, no-lead package with dimensions of 2.5mm x 2.0mm x 1.1mm.

Oscillators Feature Summary

• Ultra-miniature SMD form factor suitable for space-constrained designs
• HCMOS output signal compatible with standard digital logic interfaces
• Integrated enable and disable control function for power management

Oscillators Applications

• Portable consumer electronics requiring low-power clock sources
• Embedded systems utilizing 1.8V logic families
• Industrial control modules operating within standard commercial temperature ranges

Oscillators Procurement Notes

Verify the specific ordering suffixes to ensure compatibility with required frequency tolerance and temperature specifications. Confirm that the 1.8V supply voltage aligns with the target system's power architecture. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the lead-free packaging meets soldering process requirements for the manufacturing line.

Oscillators Selection Notes

Select this model when a small footprint and low voltage operation are critical constraints. The HCMOS output is appropriate for direct interfacing with microcontrollers or FPGAs operating at 1.8V. Consider the ±10ppm stability requirement against the system's timing budget. Evaluate the enable/disable feature necessity for battery-powered applications requiring active power states.

Oscillators Part Context

This component belongs to the TSM22 series of ultra-miniature SMD oscillators from Transko Electronics. The series focuses on providing high-frequency stability in minimal physical packages. It serves as a clock source alternative to larger through-hole or standard SMD oscillators where board real estate is limited.

Oscillators Replacement Considerations

Direct substitutes must match the 26.000 MHz frequency, 1.8V supply, and 4-SMD 2.5x2.0mm package. Verify pinout compatibility and electrical characteristics such as rise/fall times and current consumption before substitution.
