Oscillators Procurement Notes

Verify the specific suffix designation against official Transko documentation to confirm the exact frequency tolerance and package variant. Ensure that the ordering part number matches the required 18.432 MHz specification and 3.3V operation. Cross-reference the datasheet for pinout compatibility and thermal characteristics before integration into the design.

Oscillators Selection Notes

Select this component when a stable 18.432 MHz reference is required for HCMOS-compatible digital logic. Consider the ±50ppm stability and wide industrial temperature range for reliable performance in embedded environments. The enable/disable feature allows for dynamic power control in battery-operated or energy-efficient designs.

Oscillators Part Context

This model belongs to the TSM series of MEMS-based oscillators from Transko Electronics, designed for general timing needs. The series covers frequencies from 1MHz to 137MHz with various SMD packages. It serves as a drop-in replacement for discontinued Epson VG-1201CA models, offering fit, form, and functional equivalence.

Oscillators Replacement Considerations

Transko recommends the TSMV series as a direct drop-in replacement for the discontinued Epson Toyocom VG-1201CA model, ensuring identical fit, form, and function.
