ORSO42G5-1BMN484I

The ORSO42G5-1BMN484I is an ORCA® Series 4 reconfigurable embedded SoC FPGA optimized for high-speed backplane interfaces. It integrates FPGA logic with four 0.6–2.7 Gbps SERDES channels and clock-and-data-recovery circuitry to support SONET and other high-speed interconnect applications.

Designed for industrial deployment, the device delivers a compact, surface-mount 484-BBGA footprint with a broad I/O and memory complement for implementing backplane framing, scrambling/descrambling, cell processing and custom protocol logic.

Key Features

• Logic Capacity — 10,368 logic elements (FPGA user logic) organized across 1,296 PFUs for flexible programmable resources.
• Embedded Memory — 113,664 bits of on-chip RAM (approximately 0.114 Mbits), plus two 4K × 36 RAM blocks in the embedded core accessible by FPGA logic.
• High-Speed Serial I/O — Four integrated SERDES channels supporting 0.6–2.7 Gbps per lane with built-in Clock and Data Recovery (CDR); aggregate bandwidths over 10 Gbps are supported for multi-lane configurations.
• I/O and Package — 204 user I/O pins in a 484-BBGA package (supplier device package: 484-FPBGA, 23 × 23 mm); surface-mount mounting type.
• System Gate Count — Up to ~643,000 system gates depending on configuration and resource allocation.
• Operational Range — Voltage supply range from 1.425 V to 3.6 V and industrial operating temperature range of −40 °C to 85 °C.
• SONET/Backplane Functions — Hardware support for SONET data scrambling/descrambling, streamlined SONET framing, limited TOH handling and cell processing to simplify network termination and frame handling.
• Family Interoperability — Pin-compatible with related ORT42G5/ORT82G5 devices for design flexibility within the ORCA product family.
• Regulatory — RoHS compliant.

Typical Applications

• Backplane Interfaces — High-speed serial backplane links for SONET/SDH and proprietary backplane protocols using integrated SERDES and clock recovery.
• Network Termination — Terminating and processing framed network traffic with built-in SONET framing, scrambling/descrambling and TOH handling.
• Interboard Communications — Clockless high-speed interdevice communication across boards or backplanes where integrated CDR reduces the number of clock signals and simplifies clock domains.
• High-Bandwidth Data Paths — Aggregating multi-gigabit data channels for switch fabric links and line card connections using aggregate bandwidths exceeding 10 Gbps.

Unique Advantages

• Integrated High-Speed Transceivers: Four 0.6–2.7 Gbps SERDES lanes with CDR reduce external PHY requirements and simplify high-speed link design.
• Balanced Logic and Memory: 10,368 logic elements and approximately 0.114 Mbits of on-chip RAM provide a compact platform for protocol processing, cell handling and custom logic.
• Compact, Robust Packaging: 484-BBGA (23 × 23 mm) surface-mount package offers high I/O density and a small footprint for space-constrained board designs.
• Industrial Temperature Range: −40 °C to 85 °C qualification supports deployment in industrial environments where wider temperature tolerance is required.
• Family Compatibility: Pin compatibility with related ORT/ORS devices enables design reuse and scalability across different channel-count configurations.
• On-Chip SONET Support: Built-in SONET functions simplify implementation of standard and proprietary network termination without exposing SONET details to higher-level logic.
