SX7M45.000D20F30TNN

Oscillators Overview

The SX7M45.000D20F30TNN is a standard CMOS oscillator manufactured by Shenzhen SCTF Electronics, operating at a nominal frequency of 45 MHz. It utilizes a 1.8V supply voltage and features an enable/disable control function for power management. The device is housed in a compact 4-SMD package without lead. It offers a frequency tolerance of ±20ppm and a frequency stability of ±30ppm across the specified operating temperature range.

Oscillators Feature Summary

• Integrated enable and disable functionality for active power control
• CMOS output signal generation for digital logic interfacing
• Compact surface-mount design suitable for space-constrained PCB layouts

Oscillators Applications

• Digital clock signal distribution in embedded systems
• Timing reference for microcontrollers and processors
• Synchronization source for communication interfaces

Oscillators Procurement Notes

Verify that the specific suffix 'D' corresponds to the required 1.8V supply voltage variant, as other suffixes in this series may indicate different voltage levels such as 3.3V. Confirm the package dimensions match the target footprint and ensure the enable pin configuration aligns with the system's power sequencing requirements before finalizing the order.

Oscillators Selection Notes

Select this component when a 45 MHz timing source with low voltage operation is required. The ±20ppm tolerance and ±30ppm stability provide adequate precision for general digital applications. Consider the enable feature if dynamic power saving is necessary. Ensure the 1.8V supply rail is stable within the operational limits to maintain frequency accuracy.

Oscillators Part Context

This model belongs to the SX7M series of SMD oscillators from Shenzhen SCTF Electronics. The series includes variants with different frequencies, supply voltages, and package sizes. The 'D' suffix typically denotes the 1.8V supply version, distinguishing it from other voltage options like 3.3V or 2.5V found in similar part numbers within the same product line.

Oscillators Replacement Considerations

Direct substitutes include the SX7M45.000B20F30TNN (3.3V) and SX7M45.000M20F30TNN (variable voltage), provided the supply voltage difference is accommodated by the circuit design. Cross-referencing the datasheet for pin compatibility and electrical characteristics is essential when swapping between these variants.
