NZ2520SA-25.600MHZ

Overview

The NZ2520SA-25.600MHZ is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by NDK, operating at a nominal frequency of 25.6 MHz. It features a CMOS output signal and supports a supply voltage range of 1.8V to 3.6V. The device includes a standby function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.5mm x 2.0mm and a maximum height of 0.9mm. The unit is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated temperature compensation circuitry ensures stable frequency performance across varying thermal conditions.
• Configurable standby mode allows for significant power reduction when the oscillator is not actively driving the load.
• CMOS output interface provides compatibility with standard digital logic circuits.

Applications

• Portable communication devices requiring low power consumption
• Wireless sensor networks
• Mobile handsets and tablets

Procurement Notes

Verify that the specific part number matches the required frequency and package type. Confirm that the supply voltage requirements align with the target system design. Ensure the operating temperature range meets the environmental specifications of the intended application. Check for any recent product change notices or end-of-life announcements from the manufacturer.

Selection Notes

Select this component when a small form factor TCXO is needed for applications demanding high frequency stability over a wide temperature range. Consider the CMOS output level and standby current specifications against the system's power budget. Evaluate the 4-SMD package dimensions against the available PCB space constraints.

Part Context

This component belongs to the NZ2520SA series of surface-mount TCXOs from NDK. The series is designed for applications where size and power efficiency are critical. It utilizes AT-cut crystal technology for superior frequency stability compared to standard crystals without compensation.

Replacement Considerations

Direct substitutes include other 25.6 MHz TCXOs in the 2520 package footprint from manufacturers such as Epson, Seiko Instruments, or KDS. Verify pinout compatibility and electrical parameter equivalence before substitution.
