QTM532-133.000MDE-T

Overview

The QTM532-133.000MDE-T is a standard CMOS crystal oscillator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 133 MHz and utilizes a 4-SMD, no-lead package with dimensions of 5.0mm x 3.2mm. The device functions at a supply voltage of 1.8V and includes an enable/disable control feature. Frequency stability is specified at ±50 ppm over the commercial operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated enable and disable functionality for power management
• CMOS output signal compatibility
• Compact surface-mount package design

Applications

• High-speed digital clock generation
• Data communication interface timing
• Embedded system processor clocks

Procurement Notes

Verify that the specific suffix 'D' in the part number corresponds to the required 1.8V supply voltage and enable/disable pin configuration. Confirm the package outline matches the 5.0x3.2mm footprint requirements. Ensure the frequency tolerance of ±50ppm meets the system timing accuracy specifications before finalizing procurement orders.

Selection Notes

Select this component when a 133 MHz clock source is required with low voltage operation. The 1.8V supply requirement distinguishes it from higher voltage variants. The enable pin allows for dynamic power control, which is beneficial for battery-operated or power-sensitive designs compared to always-on oscillator alternatives.

Part Context

This oscillator belongs to the QTM532 series, which provides various frequency options within a standardized 5.0x3.2mm SMD footprint. The series supports different voltage levels and stability grades, allowing designers to maintain consistent board layouts while adjusting electrical specifications for different application needs.

Replacement Considerations

Direct substitutes include other 133 MHz CMOS oscillators in the same 4-SMD package with compatible 1.8V logic levels. Verify that any replacement also supports the -40°C to +85°C temperature range and offers similar ±50 ppm stability.
