QTM216-48.000MBD-T

Overview

The QTM216-48.000MBD-T is a surface-mount CMOS oscillator manufactured by QST, operating at a nominal frequency of 48 MHz. It utilizes a quartz resonator and features a 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The device supports a supply voltage of 3.3V and offers an enable/disable function via the 1.8V logic level interface. Frequency stability is rated at ±25ppm over the operating temperature range of -40°C to +85°C. The maximum supply current is 10mA, ensuring low power consumption suitable for compact electronic designs requiring precise timing signals.

Feature Summary

• Integrated quartz-based timing solution in a compact 2.0x1.6mm SMD package
• Supports hardware enable/disable control for power management flexibility
• Low electromagnetic interference (EMI) characteristics inherent to the series design

Applications

• High-definition video transmission systems requiring stable clock sources
• Embedded controllers and microprocessor clock inputs
• Industrial communication interfaces such as LVDS or MIPI

Procurement Notes

Verify the specific suffix 'BD' against the manufacturer's official datasheet to confirm the exact frequency tolerance and enable pin configuration. Ensure the selected variant matches the required supply voltage and operating temperature range for the target application environment. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a 48 MHz clock signal is required within a constrained PCB area. The 4-SMD no-lead package facilitates automated assembly. Consider the ±25ppm stability requirement against system timing budgets. Verify that the 3.3V supply rail is available and that the enable functionality aligns with the system's power sequencing requirements.

Part Context

This oscillator belongs to the QTM216 series from QST, designed for applications demanding low profile and reliable timing. The series typically includes variants with different frequencies and tolerances, sharing the same physical footprint and electrical interface standards. It serves as a direct replacement for standard crystal oscillators in space-sensitive consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 48MHz 2.0x1.6mm CMOS oscillators from manufacturers like TXC or SiTime, provided pin compatibility and electrical specifications match. Verify that alternative parts support the same enable/disable logic and frequency stability requirements.
