SX3M120.000B20F30TNN

Oscillators Overview

The SX3M120.000B20F30TNN is a CMOS crystal oscillator manufactured by Shenzhen SCTF Electronics. It operates at a nominal frequency of 120 MHz with a supply voltage of 3.3V. The device features enable and disable control functionality. It utilizes a 4-SMD, no-lead package (SMD3225-4P). The unit supports an operating temperature range from -40°C to +85°C. Maximum supply current is specified as 40mA. Frequency stability is documented at ±50ppm in some sources, while others indicate ±20ppm.

Oscillators Feature Summary

• CMOS output signal generation for digital circuits
• Integrated enable and disable control pin for power management
• Surface-mount design suitable for automated assembly

Oscillators Applications

• General-purpose clock source for embedded systems
• Timing reference for microcontrollers and processors
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance requirement against available documentation variants, as sources cite both ±20ppm and ±50ppm. Confirm the exact package dimensions match the SMD3225-4P footprint. Ensure the 3.3V supply voltage aligns with the target circuit design. Check lead time and minimum order quantities directly with the distributor or manufacturer, as these are not fixed in public data.

Oscillators Selection Notes

Select this component when a 120 MHz CMOS clock signal is required within a -40°C to +85°C industrial temperature range. The enable/disable feature allows for dynamic power control. Compare against other models in the SX3M series for alternative frequencies. Ensure the 40mA maximum current consumption fits the system power budget. Verify compatibility with the host device's input logic levels.

Oscillators Part Context

This oscillator belongs to the SX3M series from Shenzhen SCTF Electronics, which includes various frequencies such as 12 MHz and 100 MHz. The series shares similar packaging and voltage specifications. It is distinct from passive crystals, providing a ready-to-use square wave output. The model number encodes the frequency and package type.

Oscillators Replacement Considerations

Direct substitutes include other 120 MHz CMOS oscillators in the same package family. Models like SX3M66.667B20F30TNN offer different frequencies but similar form factors. Cross-reference electrical parameters carefully, especially frequency tolerance and supply current. Ensure the replacement maintains the enable/disable functionality if required by the design.
