SX3M66.000B20F30TNN

Oscillators Overview

The SX3M66.000B20F30TNN is a surface-mount crystal oscillator manufactured by Shenzhen SCTF Electronics. It operates at a nominal frequency of 66 MHz with a CMOS output interface. The device requires a 3.3V supply voltage and draws a maximum operating current of 20 mA. Frequency stability is rated at ±20 ppm over normal conditions and ±30 ppm across the full temperature range. It functions within an operating temperature range of -40°C to +85°C and utilizes an SMD3225-4P package.

Oscillators Feature Summary

• CMOS output signal generation for digital logic compatibility
• Surface-mount design for automated PCB assembly
• Wide industrial temperature operation capability

Oscillators Applications

• General-purpose clock source for microprocessors
• Timing reference for communication interfaces
• Clock signal provision for embedded control systems

Oscillators Procurement Notes

Verify the manufacturer designation as Shenzhen SCTF Electronics or SCTF (Xingtong Time Frequency) against official component markings. Confirm the specific suffix B20F30 corresponds to the required ±20 ppm initial accuracy and ±30 ppm total stability specifications. Ensure the package type matches the SMD3225-4P footprint requirements for your board layout.

Oscillators Selection Notes

Select this component when a 66 MHz CMOS clock signal is required for digital circuits. The 3.3V supply voltage must align with the target system's power rails. Consider the ±30 ppm total stability if precise timing synchronization is critical across extreme environmental variations. The SMD3225-4P package size should be evaluated against available PCB real estate constraints.

Oscillators Part Context

This part belongs to the series of active surface-mount oscillators produced by SCTF. These devices are designed to replace discrete crystal and resonator combinations, offering integrated frequency generation in a compact form factor. The model number indicates specific electrical characteristics including frequency, stability, and package type.

Oscillators Replacement Considerations

Direct substitutes must match the 66 MHz frequency, CMOS output, 3.3V supply, and SMD3225-4P package. Verify that alternative components meet the same ±20 ppm/±30 ppm stability ratings and -40°C to +85°C operating temperature range to ensure functional equivalence.
