SX5M7.3728B10F20TNN

Oscillators Overview

The SX5M7.3728B10F20TNN is a CMOS crystal oscillator manufactured by Shenzhen SCTF Electronics, designed for surface-mount applications in the 7050 package (7.0x5.0mm). It operates at a nominal frequency of 7.3728 MHz with a supply voltage of 3.3V. The device features a frequency stability of ±10 ppm at 25°C and ±20 ppm over the full operating temperature range of -40°C to +85°C. Typical current consumption is 10 mA. The output is CMOS compatible, enabling direct connection to microcontrollers without additional level shifting components.

Oscillators Feature Summary

• CMOS output interface compatible with standard digital logic levels
• Integrated enable/disable control functionality via pin configuration
• Industrial-grade reliability with high resistance to vibration and thermal cycling
• RoHS compliant construction suitable for lead-free soldering processes

Oscillators Applications

• Industrial serial communication gateways (RS-485/UART)
• Microcontroller system clock generation
• Low-speed analog-to-digital converter timing references
• Embedded industrial control modules

Oscillators Procurement Notes

Verify the specific suffix 'TNN' against the manufacturer's latest datasheet to confirm tape-and-reel packaging and exact electrical tolerances. Ensure the ordering part number matches the required frequency stability grade (+/-10ppm vs +/-20ppm) as suffixes may indicate different performance tiers. Confirm that the 7050 footprint aligns with the target PCB design constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a stable 7.3728 MHz reference is required for baud rate generation in serial interfaces, minimizing error rates below 0.1%. The 3.3V supply requirement suits modern low-power industrial designs. Consider the +/-10 ppm initial tolerance for precision timing needs and verify that the 10 mA current draw fits within the system power budget. The CMOS output eliminates the need for external buffer circuits compared to older oscillator types.

Oscillators Part Context

This model belongs to the SX7M series from Shenzhen SCTF Electronics, which specializes in surface-mount crystal oscillators. The series is engineered for industrial environments requiring robust performance under thermal stress. The 7.3728 MHz frequency is a standard choice for UART and RS-485 applications due to its divisibility into common baud rates. The 7050 package provides a balance between size and thermal dissipation for embedded systems.

Oscillators Replacement Considerations

Cross-reference with other SCTF models in the SX7M series for pin-compatible alternatives. Verify that any substitute maintains the 7.3728 MHz frequency and 3.3V CMOS output characteristics. Ensure the replacement part supports the same -40°C to +85°C operating range and meets the required +/-10 ppm stability specification for critical timing applications.
