NT3225SA-19.200000MHZ

Overview

The NT3225SA-19.200000MHZ is a Voltage-Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by NDK. It operates at a nominal frequency of 19.2 MHz with a clipped sine wave output. The device supports supply voltages of +1.8V and +3.0V, consuming a maximum current of 2mA. It features a frequency stability of ±2.5ppm over the operating temperature range of -10°C to +75°C. The component is housed in a compact 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a maximum height of 1.00mm.

Feature Summary

• Integrates voltage-controlled temperature compensation for enhanced frequency stability across varying thermal conditions.
• Supports low power supply voltages including standard +1.8V and +3.0V specifications.
• Delivers a clipped sine wave output signal suitable for digital clocking applications.

Applications

• Smartphone timing circuits
• Mobile phone baseband processors
• Wireless module synchronization
• GPS/GNSS module reference clocks

Procurement Notes

Verify the specific suffix code associated with the part number to confirm exact electrical tolerances and pinout configurations, as variations exist within the NT3225SA series. Ensure that the design environment supports the required supply voltage levels and that the PCB layout accommodates the 4-SMD no-lead package dimensions. Confirm RoHS compliance status if required by regional regulations.

Selection Notes

Select this component when high frequency stability is required in space-constrained mobile devices. The VCTCXO architecture provides better performance than standard TCXOs while maintaining lower power consumption than higher-end alternatives. Consider the ±2.5ppm stability specification against the system's jitter budget and ensure the clipped sine wave output is compatible with the input threshold of the target microcontroller or RF front-end.

Part Context

This oscillator belongs to the NT3225SA series from NDK, designed specifically for portable electronics. The series emphasizes miniaturization with a cubic volume of 0.007 cm³ and weight of 0.024g. It utilizes lead-free soldering processes compliant with Directive 2011/65/EU and Directive (EU) 2015/863, making it suitable for modern surface-mount assembly lines.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 19.2 MHz frequency, VCTCXO type, 4-SMD package, and ±2.5ppm stability specifications.
