Procurement Notes

Verify the manufacturer designation carefully, as the model number appears in listings associated with both QST and TXC Corporation. Confirm the specific datasheet version matches the required pinout and electrical characteristics. Ensure the order quantity aligns with the reel packaging specifications typically found in distributor catalogs. Check regional availability restrictions before finalizing procurement plans.

Selection Notes

Select this component when a 24.576 MHz clock source is required with CMOS output compatibility. The ±50 ppm stability specification suits general-purpose timing applications rather than high-precision requirements. Consider the 3.3V operating voltage constraint against the target system's power rails. The enable/disable feature offers flexibility for power-sensitive designs requiring clock gating capabilities.

Part Context

This oscillator belongs to the QTM750 series, which provides standardized surface-mount solutions for various frequency needs. The series includes multiple frequency options such as 10 MHz, 112 MHz, and 32.768 MHz, all sharing similar physical dimensions and electrical characteristics. This consistency simplifies inventory management and board layout processes for manufacturers utilizing different clock frequencies within the same product line.

Replacement Considerations
