Overview
The QTM216E-24.576MDM-T is a standard clock oscillator manufactured by TXC Corporation, operating at a frequency of 24.576 MHz with CMOS output. It features a supply voltage of 1.8V and a frequency stability of ±50ppm across an operating temperature range of -40°C to 125°C. The device utilizes a 2.0x1.6mm surface-mount ceramic package and has a maximum supply current of 10mA.
Feature Summary
- Integrates low EMI functionality within a compact 2016 package to reduce electromagnetic interference without additional external components.
- Supports phase modulation mode via Pin 1 control to spread clock spectrum and lower radiation peaks for EMC compliance.
Applications
- High-definition security camera systems
- Consumer display interfaces including MIPI and LVDS
- Wearable electronic devices requiring compact form factors
Procurement Notes
Verify the manufacturer designation carefully, as sources list both TXC Corporation and QST for this part number. Confirm that the specific suffix corresponds to the required voltage and frequency parameters before ordering. Ensure compatibility with the target system's power supply and interface requirements.
Selection Notes
Select this component when design constraints require a low-profile 2.0x1.6mm footprint combined with strict EMI performance. It is suitable for applications needing 24.576 MHz timing with 1.8V operation and industrial temperature resilience. Consider the GPIO-controlled EMI reduction feature if board space for filtering is limited.
Part Context
This oscillator belongs to the QTM216E series, which provides low EMI solutions in a small SMD ceramic package. The series supports various frequencies up to 40MHz and multiple supply voltages, designed to meet stringent EMC standards in portable and automotive electronics without increasing BOM complexity.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other 2016 low EMI oscillators based on pinout and electrical specifications.
FAQ
How is the low EMI mode activated?
The low EMI mode is activated by pulling Pin 1 (phase modulation control) low via a GPIO. The pin has an internal pull-up resistor, so leaving it floating or high enables standard clock mode.
What is the impact of EMI mode on frequency accuracy?
Enabling the phase modulation mode introduces a slight frequency deviation, typically around ±0.3% to ±0.7% depending on voltage and frequency, which remains within acceptable limits for most interface protocols like MIPI and LVDS.
