LatticeECP3 supports CPRI (Common Public Radio Interface) low latency mode operation and the FIFO bridge in the SERDES/PCS is bypassed. The conditions are that the operation runs at full synchronous mode and data is handed off from SerDes/PCS to FPGA ...
The SPI4.2 interface uses FPGA LVDS I/Os. These FPGA LVDS I/Os meet Lattice's Hot-Socketing specification. Lattice's Hot-Socketing specification specifies that users can plug into an active bus without damaging the device. Please note that there are ...
Lattice Technical Support Expectation Please be advised that highest priority for Lattice Technical Support will be given to 1. Software which is not working as expected or suspected bugs. We recommend that customers use the latest software tools and ...
Lattice currently recommends the following for implementing Gigabit Ethernet interfaces: CertusPro-NX FPGAs: Use SERDES-based SGMII or RGMII Certus-NX, MachXO5-NX, and CrossLink-NX: Use RGMII These recommendations are based on updated LVDS-based ...
Glitch Fliter is used to prevent short-duration events of glitches, This is used to prevent False tripping on noise in a system. GLITCHFilter in device constraints , enables 1ns glitch filtering.
Description: Nexus device family has a default I2C slave address of 0x40 and you are allow to modify it based on your requirement. Solution: To permanently modify the I2C address, you can modify the desired value in .fea file and use the Programmer ...
