Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required frequency tolerance and load capacitance specifications for your design. Confirm that the 4-SMD no-lead package footprint aligns with your PCB layout constraints. Ensure the supply voltage provided to the VCC pin remains within the 1.62V to 3.63V operational window to maintain frequency accuracy. Check that the enable pin logic levels are compatible with your microcontroller or FPGA GPIO outputs.

Oscillators Selection Notes

Select this component when a stable 66.6666 MHz reference is needed for high-speed data interfaces. It is suitable for designs requiring dual-voltage support across different subsystems. Consider this part if space constraints favor a compact 7050 SMD package. Evaluate the 30mA current consumption against your total system power budget. Ensure the ±20ppm stability meets the jitter requirements of your communication protocol.

Oscillators Part Context

This oscillator belongs to the SX7M series from Shenzhen SCTF Electronics, which focuses on industrial-grade surface-mount crystal oscillators. The series is characterized by wide voltage ranges and robust performance across extended temperature zones. These components are commonly used in telecommunications and industrial automation equipment where timing precision and environmental resilience are critical for system stability.

Oscillators Replacement Considerations

Direct substitutes must match the 66.6666 MHz frequency, 4-SMD package, and ±20ppm stability. Verify that alternative parts support the same 1.62V-3.63V voltage range and CMOS output type. Ensure the replacement maintains the -40°C to +85°C operating temperature rating. Cross-reference pinouts and enable logic polarity to guarantee functional compatibility.
