Oscillators Procurement Notes

Verify that the specific suffix '36.6666M' matches the required frequency exactly, as this series offers multiple frequency options. Confirm the package type is 4-SMD No Lead and that the 3.3V HCMOS interface aligns with the target circuit design. Ensure the enable/disable feature is utilized correctly in the schematic. Cross-reference the manufacturer's latest datasheet to confirm active status and any potential obsolescence notices before finalizing procurement.

Oscillators Selection Notes

Select this component when a precise 36.6666 MHz clock source is required with low power consumption and small form factor constraints. The MEMS-based construction offers robustness against shock and vibration compared to traditional ceramic resonators. Consider the enable/disable pin if system-level power saving is a priority. Verify that the HCMOS output swing is compatible with the receiving digital input thresholds of the connected microcontroller or FPGA.

Oscillators Part Context

This part belongs to the TSM series of oscillators from Transko Electronics, which are positioned as drop-in replacements for discontinued models from other manufacturers such as Epson Toyocom. The series leverages MEMS technology to provide high stability and reliability in a small footprint. It competes in the market for standard XO solutions where size and power efficiency are critical factors for modern electronic designs.

Oscillators Replacement Considerations

Transko suggests the TSMV series as a drop-in replacement for the discontinued Epson Toyocom VG-1201CA model. Users replacing older components should verify fit, form, and function compatibility. Ensure that the electrical characteristics of the substitute match the original design requirements before implementation.
