Programmable Oscillators Procurement Notes

Verify the specific programmed frequency required for your application, as this is a programmable device. Confirm that the CMOS output level matches your system's input requirements. Ensure the 3.3V supply voltage aligns with your design constraints. Check the lead time for programming services if ordering through distributors offering blank parts. Validate the 6-SMD package dimensions against your PCB footprint specifications.

Programmable Oscillators Selection Notes

Select the 591CD-BDG when a CMOS output is preferred over differential formats like LVDS or LVPECL. Choose this part for applications requiring ±7ppm stability rather than the wider tolerances found in other series variants. Consider the 3.3V supply requirement compared to 2.5V options in the same family. Evaluate the need for programmability versus fixed-frequency alternatives based on production volume and flexibility needs.

Programmable Oscillators Part Context

The 591CD-BDG belongs to the Si591 family of single-frequency general-purpose oscillators. This series provides various output formats including CMOS, LVDS, and LVPECL across different supply voltages. The CD suffix indicates the CMOS output type and 3.3V operation. The BDG suffix typically denotes a tape-and-reel packaging option suitable for automated assembly processes.

Programmable Oscillators Replacement Considerations

Direct substitutes within the Si591 family include 591CA-BDG (LVPECL, 3.3V), 591CB-BDG (LVDS, 3.3V), and 591CC-BDG (LVDS, 2.5V). For CMOS output at 2.5V, consider the 591CE-BDG variant. Fixed-frequency equivalents may be available by specifying exact frequencies in the model number. Verify pin compatibility and electrical parameters before substitution.
