Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with the required design tools, such as ispLEVER System software, for successful implementation and configuration of the embedded core logic.

Field Programmable Gate Array Selection Notes

Select this component when a combination of high-speed serial connectivity and substantial programmable logic is required on a single chip. Consider the pinout compatibility with the ORSO42G5 if SONET scrambling functionality is needed in a future design revision without changing the board layout.

Field Programmable Gate Array Part Context

This device belongs to the ORCA Series 4 family of Field Programmable System Chips (FPSCs). It shares the same FPGA architecture and pinout as the ORSO42G5, which specializes in SONET cell processing. The ORT42G5 variant focuses on general-purpose high-speed serial transmission protocols like XAUI and Fibre Channel.

Field Programmable Gate Array Replacement Considerations

The ORSO42G5 is pin-compatible but offers different embedded core functionality focused on SONET scrambling rather than general serial transmission.
