NZ2520SA-20.000000MHZ

Overview

The NZ2520SA-20.000000MHZ is a CMOS Temperature Compensated Crystal Oscillator (TCXO) manufactured by NDK. It operates at a nominal frequency of 20 MHz with a frequency stability of ±30 ppm. The device supports a supply voltage range of 1.8V to 3.6V, typically 3V, and draws a maximum supply current of 8mA. It features a standby function for power-down capability. The component is housed in a compact 4-SMD, no-lead package measuring 2.50mm x 2.00mm with a maximum height of 0.90mm. It is designed for surface mount installation and operates within a temperature range of -10°C to +60°C.

Feature Summary

• Integrates a crystal base resonator for consistent frequency regulation and temperature compensation.
• Includes a standby function allowing for power-down operation to conserve energy.
• Supports CMOS output logic compatible with standard digital interfaces.

Applications

• Portable electronic devices requiring stable clock sources
• Mobile communication equipment
• Digital media players and handheld devices

Procurement Notes

Verify the specific operating temperature range (-10°C to +60°C) against your application requirements, as this model does not cover the full industrial range. Confirm that the 8mA maximum supply current aligns with your system's power budget. Ensure the PCB footprint matches the 2.50mm x 2.00mm x 0.90mm SMD package dimensions. Check for any specific reflow soldering profile recommendations from the manufacturer datasheet to ensure joint integrity.

Selection Notes

Select this component when a compact TCXO solution is needed for portable applications where size constraints are critical. It is suitable for designs requiring a 20 MHz reference with moderate stability (±30 ppm). Consider the standby feature if power management during idle states is a priority. Compare against standard XO models if temperature compensation is not required, or higher-stability TCXOs if tighter tolerance is necessary.

Part Context

This part belongs to the NZ2520SA series of ultra-compact, low-power crystal oscillators from NDK. The series is designed for mobile and portable electronics, offering a balance between size, power consumption, and frequency stability. It utilizes AT-cut quartz crystals for reliable performance in consumer-grade environments.

Replacement Considerations

Public confirmed substitute part numbers were not identified in the provided source material. Verify compatibility with alternative 20MHz TCXOs based on pinout, voltage, and stability specifications.
