• Beacons and rescue systems

Oscillators Procurement Notes

Verify the specific suffix codes against official Transko documentation to ensure compatibility with required voltage levels and output types. Confirm that the ±50ppm stability rating meets system requirements. Ensure the -40°C to 85°C temperature range aligns with the intended operational environment before procurement.

Oscillators Selection Notes

Select this component when a low-voltage, low-current HCMOS oscillator is required for space-constrained designs. The 1.8V supply and 1mA typical current make it suitable for battery-powered applications. Verify that the ±50ppm stability is sufficient for the target clocking needs compared to higher precision alternatives.

Oscillators Part Context

This part belongs to the TSM series of ultra-miniature SMD HCMOS oscillators from Transko Electronics. The series offers wide frequency ranges and AEC-Q200 qualification options. It serves as a drop-in replacement for discontinued models like the Epson VG-1201CA, providing fit, form, and function compatibility.

Oscillators Replacement Considerations

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