ORT42G5-1BMN484I

The ORT42G5-1BMN484I is an ORCA® ORT42G5-series Field Programmable Gate Array (FPSC) from Lattice Semiconductor built on the Series 4 reconfigurable embedded SoC architecture. The device integrates an FPGA fabric with four SERDES transceivers and embedded system resources to support high-speed serial backplane data transmission and similar board-level interconnect tasks.

Designed for applications such as XAUI, Fibre Channel and Ethernet links, the ORT42G5 family delivers up to 3.7 Gbps per SERDES channel with built-in Rx Clock and Data Recovery (CDR), embedded 8b/10b support, and a clockless high-speed interface to simplify multiboard clock-domain design.

Key Features

• Core Logic  10,368 logic elements (user LUTs) organized across 1,296 programmable function units (PFUs), delivering flexible FPGA resources for glue logic, protocol handling, and custom datapaths.
• High‑Speed SERDES  Four SERDES channels with per-channel operation up to 3.7 Gbps, full‑duplex data paths, Rx CDR and transmitter preemphasis for reliable backplane links (tested across 26 inches of FR‑4).
• Embedded Memory  Approximately 0.114 Mbits (113,664 bits) of on-chip RAM and multiple embedded block RAM (EBR) resources to support FIFOs, packet buffering and alignment functions.
• I/O and Protocol Support  204 user I/O pins with built‑in 8b/10b encoding/decoding and link state machines for XAUI and Fibre Channel protocol support as documented for the ORT42G5 family.
• System Integration  Includes features for multi-channel alignment, MUX/DEMUX blocks, and embedded system bus interfaces to streamline integration with host processors and switch fabrics.
• Package, Power and Environmental  Surface-mount 484‑BBGA package (484‑FPBGA, 23×23). Supply voltage range 1.425 V to 3.6 V. Industrial grade operation from −40 °C to 85 °C. RoHS compliant.

Typical Applications

• Backplane Interconnects  High-speed, clockless interdevice communication across backplanes for system-level data paths using the integrated SERDES and CDR features.
• 10 Gigabit Ethernet (XAUI) Bridges  Implement XAUI interfaces with configurable back-end logic and embedded 8b/10b support for 10G Ethernet bridging and aggregation.
• Storage and Fibre Channel Links  Support for Fibre Channel link state machines and 8b/10b encoding makes the device suitable for storage fabric and SAN interface functions.
• Line Card to Switch Fabric Connectivity  Use the multi-channel SERDES and alignment FIFOs to provide full backplane data connections and protection link configurations between line cards and switch fabrics.

Unique Advantages

• Integrated High‑Speed Transceivers: Four embedded SERDES channels (up to 3.7 Gbps) reduce the need for external transceiver ICs and simplify high-speed link designs.
• Built‑in Clock Recovery and Protocol Support: Rx CDR, transmitter preemphasis, embedded 8b/10b encoding/decoding and link state machines streamline implementation of Ethernet and Fibre Channel interfaces.
• Balanced Logic and Memory Resources: 10,368 logic elements plus approximately 0.114 Mbits of embedded RAM support mixed logic and buffering needs for packet handling and alignment.
• Wide Supply and Temperature Range: Operates from 1.425 V to 3.6 V and across an industrial −40 °C to 85 °C temperature range for deployment in demanding board-level environments.
• Compact Surface‑Mount Package: 484‑BBGA (23×23) packaging provides a high I/O count (204 pins) in a compact footprint for space-constrained systems.
• Standards‑oriented Feature Set: Designed features for XAUI, Fibre Channel and backplane signaling match common networking and storage interface requirements.
