TSM22-H50CQ18ST-1.000M

Oscillators Overview

The TSM22-H50CQ18ST-1.000M is a surface-mount crystal oscillator manufactured by Transko Electronics, Inc. It operates at a nominal frequency of 1.000 MHz with an HCMOS output interface. The device requires a 1.8V supply voltage and draws a maximum current of 15mA. Frequency stability is specified at ±50ppm over the operating temperature range of -40°C to +85°C. The component supports enable/disable functionality and is housed in a compact SMD package suitable for space-constrained designs.

Oscillators Feature Summary

• HCMOS digital output interface for direct logic integration
• Enable/Disable control capability for power management
• Crystal-based resonator technology ensuring stable frequency generation

Oscillators Applications

• General-purpose clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Low-power portable electronic devices requiring precise timing

Oscillators Procurement Notes

Verify the specific ordering suffix and reel configuration when placing orders, as the part number may include tape-and-reel designations. Confirm that the required supply voltage matches the 1.8V specification strictly. Ensure the operating environment remains within the -40°C to +85°C range to maintain the stated ±50ppm frequency stability. Cross-reference the package dimensions against the mechanical drawing to confirm board layout compatibility before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-frequency, low-voltage HCMOS clock source is required. The 1.8V supply requirement makes it suitable for modern low-power digital circuits. Consider the ±50ppm stability limit for applications not requiring high-precision timing. Verify that the surface-mount package fits the available PCB footprint. Evaluate the 15mA current consumption against system power budgets to ensure efficiency requirements are met.

Oscillators Part Context

This oscillator belongs to the TSM22 series from Transko Electronics, which utilizes MEMS or crystal technology for frequency generation. The series offers various frequencies and supply voltages, including 3.3V options. The TSM22 line is designed for general-purpose timing applications where moderate stability and low cost are prioritized over ultra-low phase noise or extreme temperature performance found in higher-end TCXO or OCXO families.

Oscillators Replacement Considerations

Transko recommends the TMM series as a potential drop-in replacement for discontinued oscillator models, though specific electrical matching is required. For Epson Toyocom VG-1201CA discontinuations, the TSMV series is suggested as a fit-form-function alternative. Verify pinout compatibility and electrical specifications carefully when substituting with any third-party or internal Transko alternatives.
