ORSO42G5-2BM484I

The ORSO42G5-2BM484I is an ORCA® Series 4 field programmable gate array (FPGA) device optimized for high-speed backplane interfaces. Built on the Series 4 reconfigurable embedded SoC architecture, the device integrates programmable logic, embedded memory, and high‑speed SERDES channels targeted at SONET/backplane and other high‑bandwidth interconnect applications.

This industrial‑grade surface‑mount device delivers 10,368 logic elements, 204 user I/O pins and built‑in SERDES and CDR functionality to support aggregated multi‑Gbps links, while operating across a wide supply range and industrial temperature window for robust deployment.

Key Features

• Series 4 SoC architecture – Reconfigurable embedded System‑on‑a‑Chip architecture for integration of FPGA logic and backplane transceiver functions.
• Programmable logic density – 10,368 logic elements (1296 PFUs) and up to 643,000 system gates for implementing complex custom logic and protocol processing.
• Embedded memory – Approximately 113,664 bits of on‑chip RAM; datasheet notes two 4K×36 (144K‑bit each) RAM blocks in the embedded core accessible by FPGA logic.
• High‑speed serial interfaces – Four integrated SERDES channels supporting 0.6 to 2.7 Gbps per channel with built‑in clock and data recovery (CDR) for backplane and SONET interfaces.
• I/O and package – 204 user I/O in a 484‑BBGA (484‑FPBGA 23×23) package, surface mount mounting for high‑density board designs.
• Power and temperature – Wide supply range from 1.425 V to 3.6 V and industrial operating temperature range of −40 °C to 85 °C.
• SONET/SDH support (family level) – Family datasheet documents SONET scrambling/descrambling, streamlined framing and limited TOH handling suitable for backplane SONET interfaces; built‑in CDR simplifies clock domain handling.
• Regulatory status – RoHS compliant.

Typical Applications

• Backplane interconnects – Implement high‑speed multi‑Gbps links and aggregation channels between line cards and switch fabrics using integrated SERDES and CDR.
• SONET/SDH networking modules – Terminate or interface SONET streams with on‑device scrambling/descrambling, framing and programmable protocol logic.
• High‑density FPGA logic – Deploy custom packet processing, framing, or proprietary cell processing across an FPGA fabric with significant gate and RAM resources.
• Multi‑board systems – Use built‑in clock recovery to simplify clock domains and reduce backplane signal count in multi‑board network systems.

Unique Advantages

• Integrated high‑speed transceivers: Four SERDES channels with CDR reduce external device count and simplify board-level clocking for backplane links.
• Substantial programmable resources: 10,368 logic elements and up to 643,000 system gates enable complex logic, protocol stacks and custom data processing on a single device.
• Compact, high‑I/O package: 484‑BBGA (23×23) package provides 204 user I/O for dense interconnects while keeping board footprint compact.
• Industrial reliability: −40 °C to 85 °C operating range and RoHS compliance support deployment in industrial network equipment.
• Flexible power envelope: Wide supply range (1.425 V to 3.6 V) accommodates varied IO standards and system power architectures.

Why Choose ORSO42G5-2BM484I?
