QT216S-48.000MEEC-T

Overview

The QT216S-48.000MEEC-T is a surface-mount crystal oscillator manufactured by QST, operating at a nominal frequency of 48 MHz. It features a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm. The device offers a frequency stability of ±10ppm at 25°C and maintains ±10ppm over the temperature range of -20°C to +70°C. It utilizes a CMOS output interface and is designed for low electromagnetic interference applications within standard electronic circuits.

Feature Summary

• Compact 2.0mm x 1.6mm surface-mount footprint suitable for space-constrained designs
• High frequency stability of ±10ppm across specified operating temperatures
• CMOS output configuration optimized for low electromagnetic interference

Applications

• Clock generation for microprocessors and microcontrollers
• Timing reference for communication interfaces such as USB or Ethernet
• Synchronization sources for digital signal processing systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and output drive levels. Confirm that the package variant matches the PCB footprint requirements. Check for any recent revisions in the component specification that may affect thermal or electrical performance parameters before finalizing procurement orders.

Selection Notes

Select this component when a precise 48 MHz timing source is required in a minimal surface-mount form factor. Ensure the application environment stays within the -20°C to +70°C operational range to maintain the specified ±10ppm stability. Verify that the system power supply and load conditions align with the oscillator's electrical characteristics to guarantee reliable startup and continuous operation.

Part Context

This part belongs to the QT216S series of low-profile crystal oscillators from QST. The series is characterized by its small 2.0x1.6mm package size and CMOS output options. Variants within the series differ primarily by their nominal frequency and specific temperature stability ratings, allowing designers to choose the appropriate model based on timing accuracy and physical space constraints.

Replacement Considerations

Direct replacements must match the 48 MHz frequency, 4-SMD no-lead package, and ±10ppm stability rating. Cross-reference pinouts and electrical specifications with alternative manufacturers' equivalent parts to ensure functional compatibility without modifying the existing circuit design.
