NZ2520SA-38.900MHZ

Overview

The NZ2520SA-38.900MHZ is a temperature-compensated crystal oscillator (TCXO) manufactured by NDK. It operates at a nominal frequency of 38.9 MHz with CMOS output logic levels. The device requires a single 3V power supply and features a standby function for power-down control. Designed for surface-mount applications, it utilizes a compact 4-SMD, no-lead package measuring 2.50mm x 2.00mm with a maximum height of 0.90mm. The component supports an operating temperature range of -10°C to +60°C.

Feature Summary

• Integrated temperature compensation ensures stable frequency performance across the specified operating temperature range.
• Built-in standby mode allows for power-down control to reduce current consumption during inactive periods.
• CMOS output interface provides standard digital signal compatibility for direct connection to microcontrollers.

Applications

• Portable communication devices requiring low power consumption
• Wireless sensor networks utilizing CMOS-compatible clock inputs
• Embedded systems needing precise timing references in compact form factors

Procurement Notes

Verify that the target circuit design accommodates the specific 3V supply voltage requirement and confirms compatibility with the CMOS output logic levels. Ensure the PCB footprint matches the 2.50mm x 2.00mm SMD dimensions and that the thermal environment remains within the -10°C to +60°C operational limits defined by the manufacturer specifications.

Selection Notes

Select this component when a small footprint TCXO is required for 38.9 MHz applications. It is suitable for designs prioritizing low power usage due to the standby feature. Verify that the system can tolerate the ±30ppm frequency stability specification and that the 6mA maximum supply current fits within the overall power budget constraints.

Part Context

This part belongs to the NZ2520SA series of surface-mount TCXOs from NDK. The series is characterized by its small 2520 package size and CMOS outputs. It serves as a precision clock source alternative to larger through-hole oscillators or less stable basic crystals, specifically targeting mobile and battery-operated electronics where space and energy efficiency are critical design parameters.
