NT1612AB-50MHZ-END5348A

Overview

The NT1612AB-50MHZ-END5348A is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by NDK. It operates at a nominal frequency of 50 MHz with a CMOS output type. The device supports a supply voltage range of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 1.6mm x 1.2mm x 0.45mm. The component is rated for an operating temperature range of -30°C to +85°C.

Feature Summary

• Integrated temperature compensation for enhanced frequency stability across varying thermal conditions
• Low voltage operation compatible with 1.8V power supplies
• Active enable/disable control pin for efficient power consumption management
• Compact surface-mount footprint suitable for space-constrained designs

Applications

• Portable consumer electronics requiring stable clock sources
• Wireless communication modules needing precise timing
• Industrial control systems operating in moderate temperature ranges
• Automotive infotainment and telematics units

Procurement Notes

Verify the specific suffix END5348A against official NDK documentation to confirm exact electrical characteristics and pinout configuration. Ensure compatibility with target voltage levels and interface requirements. Confirm that the operating temperature range meets the environmental demands of the final application. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this TCXO when superior frequency stability over temperature is required compared to standard XO oscillators. Consider the 1.8V supply constraint and the need for software-controlled power gating via the enable pin. Evaluate the small 1612 package size against available PCB real estate. Compare performance metrics such as phase noise and aging rate against alternative NDK series if stricter specifications are needed.

Part Context

This oscillator belongs to NDK's line of Temperature Compensated Crystal Oscillators (TCXOs). Unlike standard XO models like the END5359A, this variant includes internal circuitry to compensate for frequency drift caused by temperature changes. It targets applications where higher precision than basic crystal oscillators is necessary but full VCXO complexity is not required.

Replacement Considerations

Direct replacements must match the 50MHz frequency, 1.8V supply, and 1612 package. Verify if substitute parts offer equivalent or better temperature stability. Check for pin-to-pin compatibility regarding the enable/disable function. Ensure the replacement maintains the same output drive strength and form factor.
