Oscillators Procurement Notes

Verify that the specific part number matches the required CML output format and 1.8V supply voltage, as these parameters are critical for compatibility. Confirm the 7 PPM stability requirement aligns with system specifications. Ensure the 7x5mm footprint fits the PCB layout constraints. Check for any specific tape and reel packaging requirements if applicable to the manufacturing process.

Oscillators Selection Notes

Select this component when a 155.52 MHz clock signal with 7 PPM stability is required. The CML output format necessitates compatible receiver inputs. The 1.8V operating voltage must be supported by the power design. Consider the 100mA current draw for power budget calculations. The wide temperature range suits harsh environment applications. Verify OE pin 1 configuration against existing control logic.

Oscillators Part Context

This oscillator belongs to the Si591 family of standard clock oscillators from Skyworks Solutions. The family offers various frequencies and output formats including LVPECL, LVDS, and CML. The 591KD155M520DGR specifically provides CML outputs at 155.52 MHz. It shares the same 7x5mm package dimensions with other variants in the series but differs in electrical characteristics and frequency settings.

Oscillators Replacement Considerations

Direct substitutes within the Si591 series include 591KD125M000DG for 125 MHz and 591KD153M000DG for 153 MHz, provided the frequency difference is acceptable. Other Skyworks oscillators with CML outputs and similar packages may serve as alternatives if frequency and stability requirements can be adjusted.
