• Consumer electronics internal clock sources

Procurement Notes

Verify the manufacturer designation carefully, as this specific part number is associated with QST in technical documentation, though similar models exist under TXC Corporation branding. Confirm the exact suffix 'CB-T' matches the required package and tolerance specifications against the official datasheet. Ensure the order quantity aligns with the reel packaging requirements specified by the supplier. Cross-reference the Mouser catalog identifier 717-QTM53227.000MCBT for accurate sourcing channels.

Selection Notes

Select this component when a 27 MHz CMOS clock source is required in a 5.0x3.2 mm surface-mount package. It is suitable for designs needing an enable/disable pin for power optimization. Consider the -40 to +85°C operating range for industrial or wide-temperature consumer applications. Verify that the CMOS output voltage levels match the receiving logic inputs of the target system.

Part Context

This oscillator belongs to the QTM532 series of standard crystal oscillators. The series offers various frequencies and output types, including LVPECL variants like the QTM532P model. The 5.0x3.2 mm form factor is common for space-constrained PCB layouts. The product status is listed as Active, indicating ongoing production and availability for new design implementations.

Replacement Considerations

QTM532-27.000MCE-T: Different output type variant within the same series. QTM532-27.000MBE-T: Alternative suffix variant with potentially different tolerances or packages. QTM532-25.000MCB-T: Same package but different frequency (25 MHz). Verify electrical compatibility before substitution.
