QTM216J-7.3728MDJ-T

Overview

The QTM216J-7.3728MDJ-T is a surface-mount CMOS quartz oscillator manufactured by TXC Corporation, designed for precision timing applications. It operates at a nominal frequency of 7.3728MHz with a frequency stability of ±50ppm. The device is housed in a compact 4-pin CSMD package measuring 2mm x 1.6mm. It supports a supply voltage of 1.8V and features an enable/disable function. The operational temperature range extends from -40°C to +105°C, ensuring reliability in demanding environments.

Feature Summary

• Low jitter and phase noise performance for stable clock signals
• Compact surface-mount package suitable for space-constrained designs
• Integrated enable/disable functionality for power management

Applications

• Digital signal processing systems requiring precise clocking
• Communication equipment utilizing standard baud rates
• Embedded control units operating in wide temperature ranges

Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by TXC Corporation despite the model prefix often associated with other distributors. Confirm the specific suffix 'DJ' indicates the 1.8V supply variant and CMOS output type. Ensure the order specifies the correct tape and reel configuration if applicable for automated assembly processes.

Selection Notes

Select this oscillator when a 7.3728MHz reference is required for serial communication interfaces or audio sampling. The 1.8V supply requirement necessitates compatibility with low-voltage logic families. The ±50ppm stability is sufficient for most asynchronous data transfers but may require tighter tolerances for high-speed synchronous buses.

Part Context

This component belongs to the QTM series of miniature crystal oscillators. These devices are engineered to replace discrete crystal resonator circuits, offering integrated oscillator functionality in a standardized footprint. The series provides various frequency options and supply voltages to support diverse embedded system architectures.

Replacement Considerations

Direct substitutes must match the 7.3728MHz frequency, 1.8V supply, and 2x1.6mm SMD package. Verify that alternative components offer equivalent ±50ppm stability and CMOS output levels. Check for identical pinout configurations to ensure board-level compatibility without schematic modifications.
