Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage levels and output formats. Confirm that the 3.3V supply requirement aligns with the target system design. Check for RoHS compliance status if environmental regulations apply. Ensure the 4-SMD no-lead footprint matches the PCB layout specifications. Validate the enable/disable pin configuration against the microcontroller or logic interface available in the application circuit.

Oscillators Selection Notes

Select this component when a low-jitter, MEMS-based clock source is required for 8 MHz applications. The ±25 ppm stability suits general timing needs without demanding high-precision oven-controlled oscillators. The 3.3V operation makes it suitable for modern digital logic families. Consider the enable feature if dynamic power saving is necessary. The small form factor allows integration into space-constrained designs compared to larger ceramic resonators.

Oscillators Part Context

This part belongs to the TB Series of MEMS oscillators from TXC Corporation. The series offers various frequencies and packages, utilizing silicon MEMS technology for improved shock resistance over traditional quartz crystals. The TB-8.000MBD-T specifically targets standard timing applications where moderate stability and low cost are prioritized over ultra-high precision.

Oscillators Replacement Considerations

Direct substitutes may include other 8 MHz MEMS oscillators with identical 3.3V supply and CMOS outputs. Verify pinout compatibility for the 4-SMD no-lead package. Check if alternative brands offer similar ±25 ppm stability and enable/disable functionality. Ensure thermal characteristics match the -40°C to +85°C range.
