QTM532-54.000MBE-T

Overview

The QTM532-54.000MBE-T is a CMOS crystal oscillator manufactured by QST, operating at a nominal frequency of 54.0000 MHz. It features a surface-mount package with dimensions of 5.0mm x 3.2mm and a maximum height of 1.2mm. The device supports a supply voltage range of 2.2V to 3.6V and delivers a load current of up to 15mA. Frequency stability is specified at ±50ppm over the operating temperature range of -40°C to +85°C. The output type is CMOS, and it includes an enable/disable control function.

Feature Summary

• CMOS output interface for digital logic compatibility
• Integrated enable and disable control functionality
• Surface-mount design suitable for automated assembly

Applications

• General-purpose timing circuits in consumer electronics
• Clock generation for microprocessors and microcontrollers
• Data communication equipment requiring stable frequency sources

Procurement Notes

Verify the specific supply voltage requirements against your system design, as the component operates within a 2.2V to 3.6V range. Confirm that the load current specification of 15mA does not exceed your power budget constraints. Ensure the PCB footprint matches the 5.0mm x 3.2mm SMD package dimensions to guarantee proper mechanical fit and electrical connection during assembly.

Selection Notes

Select this component when a precise 54 MHz clock signal is required for CMOS-based digital systems. Consider the ±50ppm frequency stability requirement relative to your application's tolerance limits. Evaluate the power consumption profile against battery-operated or low-power designs due to the 15mA load current specification. Ensure the operating temperature range meets the environmental conditions of the final product deployment.

Part Context

This oscillator belongs to the QTM532 series from QST, which offers various frequencies in a compact 5.0x3.2mm package. The series provides CMOS outputs with enable/disable capabilities, catering to applications needing flexible clock management. It serves as a standard timing solution for embedded systems requiring reliable frequency generation without external tuning components.

Replacement Considerations

Direct substitutes include other QTM532 series variants with identical pinouts and specifications but different frequencies, such as QTM532-50.000MBE-T or QTM532-60.000MBE-T, provided the frequency difference is acceptable for the application.
