NZ2520SB-25.600MHZ

Overview

The NZ2520SB-25.600MHZ is a CMOS crystal oscillator manufactured by NDK, operating at a nominal frequency of 25.6 MHz. It features a standard output type and supports a 3V supply voltage with an integrated standby function for power-down control. The component utilizes a 4-SMD, no-lead surface-mount package with dimensions of 2.50mm x 2.00mm and a maximum height of 0.90mm. Designed for clock applications, it employs AT-cut quartz technology to ensure high frequency stability and rapid startup characteristics.

Feature Summary

• Integrates a standby function allowing for power-down control to reduce energy consumption during inactive periods.
• Utilizes AT-cut quartz resonator technology to achieve high frequency stability and fast startup times.
• Provides a standard CMOS output signal suitable for direct interfacing with digital logic circuits.

Applications

• Clock generation for microprocessors and microcontrollers
• Timing reference for communication interfaces such as UART and SPI
• Synchronization sources for digital signal processing systems

Procurement Notes

Verify the specific suffix and tolerance requirements against the system design specifications before ordering. Confirm that the 3V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD footprint matches the PCB layout guidelines provided in the official datasheet. Check for any RoHS compliance documentation if required by regulatory standards.

Selection Notes

Select this component when a compact, low-power clock source is required for digital systems. The 25.6 MHz frequency is optimal for audio sampling rates and baud rate generation. Consider the standby feature if power management is critical. The small 2520 package size makes it suitable for space-constrained portable devices.

Part Context

This part belongs to the NZ2520SB series of clock oscillators from NDK. The series is characterized by its small 2.5x2.0mm footprint and use of AT-cut crystals for stability. It is designed to replace larger through-hole or older SMD oscillators in modern consumer electronics and industrial equipment requiring precise timing.
