Oscillators Procurement Notes

Verify the specific output logic family against system requirements, as datasheets may list both LVDS and HCSL variants for similar part numbers. Confirm the exact package dimensions match the PCB footprint. Ensure the enable pin logic level aligns with the host controller voltage. Check for RoHS compliance documentation if required by project standards.

Oscillators Selection Notes

Select this component when a stable 155.52 MHz reference is needed for serial link applications. The HCSL output is preferred for direct interfacing with compatible receivers without additional termination networks. Consider the thermal management capabilities within the enclosure due to the specified operating temperature range. Evaluate power consumption constraints given the 40mA typical load current.

Oscillators Part Context

This oscillator belongs to the SX7DF series of surface-mount devices designed for demanding electronic applications. The series offers various frequencies and output types to support different system clocking needs. Shenzhen SCTF Electronics produces these components to meet industry standards for reliability and performance in consumer and industrial electronics.

Oscillators Replacement Considerations

The SX3DF155.520B20F30HNN serves as a potential substitute with identical electrical parameters but utilizes an SMD3225-6P package instead of the 7050 form factor. Verify mechanical clearance and solder mask design before swapping packages.
