SX7M32.768M20F30TNN

Oscillators Overview

The SX7M32.768M20F30TNN is a surface-mount CMOS crystal oscillator manufactured by Shenzhen SCTF Electronics. It operates at a nominal frequency of 32.768 MHz with a standard output configuration. The device supports a supply voltage range of 1.62V to 3.63V and features an enable/disable control function. Frequency stability is specified at ±30 ppm over the operating temperature range, while initial accuracy is maintained within ±20 ppm.

Oscillators Feature Summary

• CMOS output interface for digital logic compatibility
• Voltage-controlled enable and disable functionality via OE pin
• Surface-mount package design for automated assembly

Oscillators Applications

• Real-time clock circuits in embedded systems
• Microcontroller system clock sources
• Low-frequency timing references in consumer electronics

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct frequency tolerance and temperature range specifications. Confirm that the required supply voltage aligns with the 1.62V to 3.63V operational window. Ensure the application circuit properly handles the active-low enable signal if power-down states are utilized in the design.

Oscillators Selection Notes

Select this component when a precise 32.768 MHz reference is required for timekeeping or low-speed synchronization. The CMOS output eliminates the need for external buffering in many digital applications. Consider the ±30 ppm stability requirement against the environmental temperature variations expected in the final product deployment scenario.

Oscillators Part Context

This oscillator belongs to the SMD series from Shenzhen SCTF Electronics, designed for compact electronic assemblies. It serves as a standard timing element replacing discrete crystal resonators and load capacitors. The part integrates the necessary drive circuitry into a single surface-mount package, simplifying PCB layout and reducing component count.

Oscillators Replacement Considerations

Direct substitutes must match the 32.768 MHz frequency, CMOS output type, and compatible supply voltage range. Verify pinout compatibility and physical footprint dimensions before substitution. Ensure alternative parts meet the same ±30 ppm stability specification for the intended operating temperature range.
