END5875A-32M

Overview

The END5875A-32M is a temperature-compensated crystal oscillator (TCXO) manufactured by NDK. It operates at a frequency of 32 MHz and utilizes a clipped sine wave output signal. The device is designed for surface-mount applications, featuring a compact 4-SMD, no-lead package with dimensions of 2mm x 1.6mm x 0.65mm. It functions on a 3V supply voltage and offers stability specifications including ±10ppm initial accuracy and ±12ppm total frequency tolerance over temperature ranges.

Feature Summary

• Temperature-compensated design ensures stable frequency performance across varying environmental conditions.
• Compact surface-mount form factor suitable for space-constrained electronic assemblies.
• Clipped sine wave output provides a defined signal shape for digital interface compatibility.

Applications

• Wireless communication modules requiring precise timing references
• Portable consumer electronics utilizing low-voltage power supplies
• Industrial control systems needing reliable clock sources

Procurement Notes

Verify the specific orderable part number suffixes, such as TR or CT, to confirm packaging type and quantity per reel. Ensure the selected variant matches the required lead-free compliance status and active lifecycle stage. Cross-reference the datasheet for exact pinout configurations and thermal pad requirements during PCB layout implementation.

Selection Notes

Select this component when a 32 MHz reference is required in a minimal footprint SMD package. Consider the 3V operating voltage constraint against system power rails. Evaluate the ±12ppm total tolerance against system jitter budgets. Confirm that the clipped sine wave output level is compatible with downstream logic input thresholds without additional buffering.

Part Context

This TCXO belongs to NDK's series of miniature oscillators designed for high-volume consumer and industrial markets. The 4-SMD no-lead package represents a standardization effort to reduce assembly costs and improve placement accuracy compared to traditional leaded packages. It serves as a direct replacement for older 32.768 kHz or other frequency variants in similar footprints where size reduction is prioritized.

Replacement Considerations

Direct substitutes must match the 32 MHz frequency, 3V supply, and 4-SMD no-lead package dimensions. Verify equivalent temperature compensation characteristics and output waveform types. Check for pin-compatible alternatives from other manufacturers if supply chain diversification is required, ensuring electrical parameters align strictly.
