QTM252J-24.576MDJ-T

Overview

The QTM252J-24.576MDJ-T is a standard CMOS quartz oscillator manufactured by TXC Corporation and distributed by QST Products. It operates at a frequency of 24.576 MHz with a supply voltage of 1.8V. The device features an enable/disable function and offers a frequency stability of ±50ppm. It is designed for operation within a temperature range of -40°C to 105°C. The component utilizes a 4-SMD, no-lead package with dimensions of 2.5mm x 2.0mm.

Feature Summary

• Integrates an enable/disable control function for power management
• Delivers low jitter and phase noise performance in a compact surface-mount package
• Utilizes CMOS output logic compatible with standard digital interfaces

Applications

• High-speed data communication systems requiring precise clocking
• Embedded processing units needing low-power oscillation
• Consumer electronics utilizing 1.8V logic families

Procurement Notes

Verify the manufacturer origin, as this part is produced by TXC Corporation and sold under the QST distribution channel. Confirm the specific ordering suffix matches the required frequency and tolerance specifications. Ensure the package type corresponds to the 4-SMD no-lead footprint required for the target PCB design before finalizing procurement orders.

Selection Notes

Select this component when a 1.8V supply voltage is mandatory for the system architecture. The ±50ppm stability rating suits general-purpose timing applications rather than high-precision metrology. The enable/disable feature makes it suitable for battery-operated devices requiring active power state control during idle periods.

Part Context

This oscillator belongs to the QTM252J series, which represents a line of low-profile, ceramic-packaged quartz oscillators. The series is characterized by its small 2.5x2.0mm footprint and compatibility with automated surface-mount assembly processes. It serves as a direct replacement for larger through-hole or standard SMD oscillators in space-constrained designs.

Replacement Considerations

Direct substitutes include other 24.576 MHz CMOS oscillators with identical 1.8V supply requirements and 4-SMD no-lead footprints. Verify pinout compatibility and electrical parameters such as rise/fall times and load capacitance before swapping components from different manufacturers.
