7N19470002

Oscillators Overview

The 7N19470002 is a temperature-compensated crystal oscillator (TCXO) manufactured by TXC Corporation. It operates at a frequency of 19.44 MHz with a stability of 0.25 ppm across the industrial temperature range of -40°C to +85°C. The device supports supply voltages from 2.7V to 5.5V and features CMOS output logic. It includes an enable/disable control function for power management. The component is housed in a compact SMD package measuring 7.0 mm x 5.0 mm with ten pins, designed for surface-mount assembly.

Oscillators Feature Summary

• Temperature compensation ensures high frequency stability across wide thermal variations
• Integrated enable and disable functionality allows for active power management
• CMOS output interface provides compatibility with standard digital logic circuits

Oscillators Applications

• Precision timing references in communication systems
• Clock generation for embedded processors requiring stable frequencies
• Test and measurement equipment demanding low phase noise

Oscillators Procurement Notes

Verify the specific operating voltage requirements against the system design, as the device supports a range from 2.7V to 5.5V. Confirm that the application environment falls within the specified -40°C to +85°C temperature limits to maintain the guaranteed 0.25 ppm stability. Ensure the PCB footprint matches the 7.0 mm x 5.0 mm SMD package dimensions for proper mechanical fit and soldering.

Oscillators Selection Notes

Select this component when precise frequency accuracy is critical over varying temperatures. The 19.44 MHz frequency is suitable for specific video or data transmission standards. Consider the enable pin feature if power conservation is a priority. The CMOS output simplifies interfacing with microcontrollers compared to other logic families.

Oscillators Part Context

This part belongs to the TCXO category within TXC Corporation's oscillator portfolio. It differs from standard crystals by providing a complete oscillating circuit in a single package. The 7.0mm x 5.0mm form factor offers a balance between performance and board space efficiency compared to larger through-hole alternatives.

Oscillators Replacement Considerations

Direct substitutes must match the 19.44 MHz frequency, 0.25 ppm stability, and 7.0x5.0mm package. Verify equivalent voltage ranges and CMOS output types. Cross-reference with other manufacturers offering TCXOs with similar thermal compensation characteristics.
