Overview
The QTM216-48.000MDE-T is a standard CMOS oscillator manufactured by QST, operating at a frequency of 48 MHz. It features a crystal basic resonator and supports a supply voltage range including 1.8V with enable/disable functionality. The device is housed in a compact 4-SMD, No Lead package measuring 2.0x1.6mm. It offers a frequency stability of ±50ppm and operates within a temperature range of -40°C to 85°C or 125°C depending on the specific variant suffix. The maximum supply current is 10mA.
Feature Summary
- Integrated low EMI phase modulation capability for spectrum spreading
- GPIO-controlled enable/disable function via Pin 1
- Compact 2.0x1.6mm SMD ceramic package design
Applications
- High-definition security camera clock links
- MIPI and LVDS display interface timing
- Wearable electronic device synchronization
Procurement Notes
Verify the exact temperature range suffix (e.g., C for commercial, D for industrial) against project requirements. Confirm the enable/disable voltage logic matches the host GPIO levels. Ensure the 4-SMD footprint aligns with the PCB layout guidelines provided in the official datasheet to maintain signal integrity.
Selection Notes
Select this component when space constraints require a 2016 package size. Choose based on the required operating temperature range and supply voltage compatibility. Consider the integrated EMI reduction feature if EMC certification is a primary design constraint, eliminating the need for external filtering components.
Part Context
This part belongs to the QTM216E series of low EMI oscillators from QST. It shares the same physical footprint and functional architecture as other variants like the QTM216E-24.000MBM-T but differs in frequency and specific electrical characteristics. The series is designed for applications requiring precise timing in compact form factors.
Replacement Considerations
Direct substitutes include other QTM216 series parts with matching frequencies and packages. Cross-brand replacements must match the 4-SMD 2.0x1.6mm footprint, CMOS output, and 48MHz frequency while verifying pinout compatibility.
