ORSO42G5-2BM484I

Field Programmable Gate Array Overview

The ORSO42G5-2BM484I is a Field-Programmable System Chip (FPSC) from Lattice Semiconductor's ORCA Series 4 family, designed for high-speed serial backplane interfaces. It integrates four SERDES channels with built-in Clock and Data Recovery (CDR), supporting programmable data rates from 0.6 Gbps to 2.7 Gbps per channel. The device provides an aggregate bandwidth exceeding 10 Gbps and includes over 400K usable FPGA system gates. Key specifications include 10,368 Look-Up Tables (LUTs), 12 Embedded Block RAM (EBR) blocks totaling 111 Kbits, and support for STS-48/STM-16 SONET framing. It operates on a 1.5V core voltage and utilizes a 484-ball fpBGA package.

Field Programmable Gate Array Feature Summary

• Integrates four asynchronous high-speed SERDES channels with built-in CDR for clockless backplane communication.
• Supports SONET/SDH network termination with embedded framers, scramblers, and Transport Overhead handling.
• Features programmable cell processing blocks for automatic cell striping across multiple links.
• Combines ASIC-level efficiency with FPGA flexibility via the FPSC architecture.

Field Programmable Gate Array Applications

• SONET/SDH network termination devices
• High-speed backplane data transfer interfaces
• Work and protection connections between line cards and switch fabrics

Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet DS1028 to ensure correct package type and temperature grade. Confirm that the component matches the required speed grade and pinout configuration for your target application before procurement.

Field Programmable Gate Array Selection Notes

Select this device when designing systems requiring high-density logic combined with dedicated high-speed serial transceivers. It is suitable for applications needing SONET protocol handling or generic high-speed data movement without external PHY components. Consider the 484-ball package constraints during PCB layout.

Field Programmable Gate Array Part Context

This component belongs to the ORCA ORSO42G5 and ORSO82G5 family of Field-Programmable System Chips. These devices extend Lattice's high-speed serial backplane portfolio by combining SRAM-based FPGA logic with embedded standard-cell cores optimized for SONET and non-SONET applications.

Field Programmable Gate Array Replacement Considerations

The ORT42G5 and ORT82G5 are sister devices that are completely pin-compatible with the ORSO42G5 and ORSO82G5 respectively. They support 8b/10b encoding for 10 Gbit Ethernet and Fibre Channel but lack the specific SONET framing features of the ORSO series.
