Oscillators Procurement Notes

Verify the specific output format and supply voltage requirements against your system design before ordering. Confirm that the LVPECL output compatibility matches your receiver inputs. Ensure the 3.3V supply rail can support the maximum current draw of 120 mA during peak operation. Check lead times as availability may vary due to manufacturing cycles. Validate the operating temperature range meets your environmental specifications.

Oscillators Selection Notes

Select this component when a fixed 155.52 MHz clock is required with LVPECL outputs. It is suitable for designs needing I2C configurability for future adjustments or redundancy. Consider the 7x5mm SMD footprint for PCB layout constraints. Evaluate the thermal performance within the -40°C to +85°C range for your application environment. Compare power consumption against other oscillators if energy efficiency is critical.

Oscillators Part Context

This part belongs to the Si571 family of programmable oscillators, which are widely used in networking and industrial applications. The Si571 series offers flexibility through I2C control, replacing multiple fixed-frequency crystals. The 571AJC000337DGR specifically targets the 155.52 MHz frequency point, common in fiber optic and Ethernet standards. Its compact size and low profile make it ideal for space-constrained modern electronics.

Oscillators Replacement Considerations

Direct parameter-equivalent substitutes include the 571AJC000337DG variant, which shares identical electrical characteristics and pinout. Verify that any replacement maintains the same LVPECL output type and 3.3V supply requirement. Ensure the substitute part number corresponds to the same frequency and package dimensions to guarantee mechanical compatibility.
