7N19471003

Oscillators Overview

The TXC Corporation 7N19471003 is a temperature-compensated crystal oscillator (TCXO) designed for precision timing applications. It operates at a fundamental frequency of 19.44 MHz and utilizes CMOS output logic levels. The device is powered by a single 3.3V supply voltage, ensuring compatibility with standard digital logic families. It is housed in a compact 10-SMD, no-lead package, facilitating surface-mount assembly processes. This component integrates internal compensation circuitry to maintain frequency stability across varying environmental temperatures, making it suitable for systems requiring reliable clock signals without external temperature control mechanisms.

Oscillators Procurement Notes

Verify the specific datasheet revision and pinout configuration against your PCB design requirements before procurement. Confirm that the 3.3V supply voltage aligns with your system's power rails. Ensure the 10-SMD footprint matches your manufacturing capabilities. Cross-reference the part number with official TXC documentation to confirm current production status and compliance certifications such as RoHS.

Oscillators Selection Notes

Select this component when precise frequency stability is required over a defined temperature range without the complexity of oven-controlled oscillators. The CMOS output simplifies interfacing with microcontrollers and FPGAs. Consider the 19.44 MHz frequency specifically if it matches your sampling or baud rate requirements. Evaluate the thermal performance specifications against your operating environment to ensure adequate stability margins are maintained.

Oscillators Part Context

This TCXO belongs to the broader category of precision oscillators used in electronic systems where clock accuracy is critical. Unlike standard crystal oscillators, it includes active compensation elements. The 19.44 MHz frequency is often chosen for its divisibility into common data rates. The 3.3V operation reflects modern low-power design trends. The no-lead package supports high-volume manufacturing standards.

Oscillators Replacement Considerations

Consult official TXC substitution guides for direct equivalents. Verify that any alternative maintains the 19.44 MHz frequency, 3.3V supply, and CMOS output type. Check pin compatibility for the 10-SMD package to avoid redesigning the footprint. Ensure thermal compensation characteristics meet or exceed original requirements.
