High Performance Innovations

High Quality 6G SERDES

The LatticeECP4 FPGAs contain up to 16 CEI-Compliant 6 Gbps SERDES channels in both low cost wire-bonded and high performance flip chip packages, giving customers the choice to deploy the LatticeECP4 FPGA in chip to chip as well as long reach backplane applications. The SERDES channels can be operated at speeds from 155 Mbps to 6 Gbps and have been qualified for a number of wireline, wireless, and system design protocols – 10 Gigabit Ethernet, 1 Gigabit Ethernet, SGMII, XAUI, RXAUI, PCI Express 2.1, SRIO 2.0, and CPRI. Please visit the LatticeECP4 low power SERDES page for more information.

10X More Efficient MACO Communication Engines

The powerful MACO Communication Engines are hard-wired Intellectual Property (IP) blocks that implement popular communication protocols using only 10% of the silicon resources and power compared to similar implementations in other FPGA fabrics. MACO stands for ‘Multiple Access Cost Optimized,’ as these Engines can be accessed from 6G SERDES or High Speed I/Os. The LatticeECP4 Communication Engines portfolio includes solutions for PCI Express 2.1, multiple 10 Gigabit Ethernet MACs and Tri-speed Ethernet MACs, as well as Serial Rapid I/O (SRIO) 2.1. LatticeECP4 FPGAs incorporate the industry’s highest density hard IP blocks for efficient communication. The LatticeECP4 FPGAs can incorporate up to 22 Communication Engines, whereas competitive “mid-range” FPGAs have only PCI Express and/or a few Ethernet MAC IP blocks. Please visit the LatticeECP4 MACO Communication Engines page for more information.

7X More Powerful DSP Blocks

The LatticeECP4 family features powerful digital signal processing (Power sysDSP) blocks with innovations that offer 7x the performance of competitive FPGAs. These innovations enable customers to implement complex, multi-antenna wireless systems (4×4 MIMO 40 MHz) and high performance video processing algorithms in low cost, low power FPGA platforms. The fully featured LatticeECP4 DSP Blocks include 18×18 multipliers, ALUs, wide adder-trees and carry chains for cascadability. Moreover, up to 576 multiplers can be cascaded together to build complex filters. Please visit the LatticeECP4 DSP technology page for more information about the powerful LatticeECP4 FPGAs.

High Speed I/Os with Embedded CDRs

The LatticeECP4 FPGAs have 50% faster differential system I/Os (GIGA sysIOs) compared to the previous generation LatticeECP3 family. The GIGA sysIOs run at speeds up to 1.25 Gbps. With embedded clock data recovery (CDR) circuits, GIGA sysIOs can be used to implement numerous serial Gigabit Ethernet and SGMII interfaces. The GIGA sysIO CDRs conserve 6G SERDES for other high speed applications. The low cost, high performance 1066 Mbps DDR3 memory interface reduces system cost. Please visit the LatticeECP4 high speed I/O page to learn more about the broad range available.
