Overview of ORSO42G5-1BM484I – ORCA® 4 Field Programmable Gate Array (FPGA) IC 204 113664 10368 484-BBGA
The ORSO42G5-1BM484I is an ORCA® Series 4 FPGA-based backplane transceiver built on a reconfigurable embedded System-on-a-Chip (SoC) architecture. It combines programmable FPGA logic with integrated high-speed serial transceivers and clock recovery for board- and backplane-level high-speed interfaces.
Targeted at high-speed backplane and SONET/SDH interface applications, the device offers a balance of logic capacity, embedded memory, I/O density and transceiver capability suitable for network line cards, switch fabric links and other interdevice high-speed communication tasks.
Key Features
- Reconfigurable SoC Architecture Built on the Series 4 reconfigurable embedded SoC architecture to combine FPGA programmability with embedded functions and interfaces.
- Logic Capacity 10,368 logic elements and 1,296 programmable function units (PFUs) arranged in a 36×36 array to implement custom packet, framing or protocol logic.
- Embedded Memory 113,664 total RAM bits (approximately 114 Kbits) of on-chip memory for buffering, packet processing and temporary storage.
- High-Speed Serial I/O Integrated 0.6–2.7 Gbps SERDES channels with built-in Clock and Data Recovery (CDR) for clockless high-speed links and simplified backplane routing.
- I/O Density 204 user I/O pins to support diverse board-level interfaces and system connectivity.
- System Gate Count Up to 643,000 system gates for implementing extensive protocol and processing logic.
- Package and Mounting 484-ball BBGA package (484-FPBGA, 23 × 23 mm) intended for surface-mount assembly.
