Programmable Oscillators Procurement Notes

Verify the specific programmed frequency against the datasheet or manufacturer confirmation prior to ordering, as this model is custom-programmed. Ensure the 3.3V supply requirement aligns with system design constraints. Confirm the CML output compatibility with downstream logic levels. Check lead times for programmed variants as they may differ from standard stock items.

Programmable Oscillators Selection Notes

Select this component when a fixed frequency crystal is insufficient and programmability between 125 MHz and 214.999 MHz is required. The ±7 ppm stability suits applications needing tight jitter performance. Consider the CML output format for signal integrity in high-speed traces. Verify the 7mm x 5mm footprint fits the PCB layout constraints compared to other Si590 series packages.

Programmable Oscillators Part Context

This part belongs to the Si590 family of standard clock oscillators by Skyworks Solutions. It offers flexibility through programmability, unlike fixed-frequency models in the same series. The QD suffix typically denotes specific packaging or programming configurations within the Skyworks portfolio, distinguishing it from generic XO units.

Programmable Oscillators Replacement Considerations

Direct substitutes are limited due to the programmed nature of the part. Equivalent parts must match the 125-215 MHz range, ±7 ppm stability, and CML output. Consult Skyworks for current alternatives if this specific program code is unavailable.
