ORSO42G5-3BMN484C

The ORSO42G5-3BMN484C is an ORCA® Series 4 FPGA-based backplane transceiver from Lattice Semiconductor Corporation. Built on the Series 4 reconfigurable embedded System-on-a-Chip (SoC) architecture, this device integrates FPGA logic with high-speed SERDES channels and on-chip memory to support high-bandwidth board and backplane interfaces.

This device is targeted for high-speed backplane and SONET-focused designs, offering integrated clock-and-data-recovery SERDES and a dense logic fabric to implement protocol, framing, or custom data-path logic in a single surface-mount package.

Key Features

• Logic Fabric  10,368 logic elements providing programmable logic capacity for protocol handling, framing, and custom data processing.
• On‑chip Memory  Approximately 0.11 Mbits (113,664 bits) of embedded RAM for buffering, packet handling, or temporary storage within FPGA logic.
• High‑speed Serial I/O  Four integrated SERDES channels supporting 0.6 to 2.7 Gbps per channel with built‑in Clock and Data Recovery (CDR); family supports aggregate bandwidths of over 10 Gbps.
• I/O Density  204 user I/O pins to connect to backplanes, line cards, or system fabrics.
• System Gate Count  Approximately 643,000 system gates for implementing complex logic and state machines.
• Package & Mounting  484‑BBGA / supplier device package 484‑FPBGA (23×23), surface‑mount construction for compact board integration.
• Power  Wide voltage support from 1.425 V to 3.6 V to match target board power rails and level‑shifting requirements.
• Commercial Temperature Grade  Rated for 0 °C to 70 °C operation, suitable for standard commercial systems.
• Compliance  RoHS compliant.
• Design Ecosystem  Part of the ORCA family and referenced in Lattice documentation alongside ispLEVER development tools and FPSC design kit items.

Typical Applications

• SONET Backplane Interfaces  Integrated SERDES channels and CDR circuitry enable implementation of SONET/SDH framing, scrambling, and limited TOH handling directly on line cards or backplanes.
• High‑speed Backplane Links  Four-channel high-speed transceivers support multi‑Gbps interconnects for board‑to‑board or backplane data transfer without external serializers.
• Network Termination and Protocol Bridging  Embedded FPGA logic combined with SERDES make the device suitable for terminating high-speed links and converting between network formats and proprietary on‑card interfaces.
• Line Card to Switch Fabric Connectivity  Aggregate bandwidth capability and multiple channels support both work and protection connections between line cards and fabric subsystems.

Unique Advantages

• Integrated High‑Speed Transceivers:  Built‑in 0.6–2.7 Gbps SERDES with CDR reduce external component count and simplify high‑speed link design.
• Dense Programmable Logic:  10,368 logic elements and ~643k system gates provide ample resources for implementing framers, protocol logic and custom processing on‑chip.
• On‑Chip Memory for Buffers:  113,664 bits of embedded RAM support packet buffering, cell processing and temporary storage without external SDRAM.
• Flexible Power Options:  1.425–3.6 V supply range enables operation across common system voltage rails.
• Compact, Surface‑Mount Package:  484‑BBGA (484‑FPBGA / 23×23) balances I/O density and board footprint for high‑performance line‑card and switch applications.
• Commercial Temperature Rating & RoHS Compliance:  Designed for standard commercial systems and compliant with RoHS requirements.
