Basic Mode

Many applications require proprietary functionality not offered by mainstream protocols. For these applications, Intel® FPGA transceivers offer 'basic' mode. Basic mode allows access to the building blocks within the transceiver. These can be individually configured or bypassed to meet your proprietary transceiver requirements.

Tables 1 and 2 list the basic modes available in Intel FPGA transceiver devices and provide a list of the transceiver physical coding sublayer (PCS) blocks available in this mode.

Tools

Basic mode is available as a transceiver configuration option within the Intel® Quartus® Prime design software. Once you select basic mode, the Intel Quartus Prime design software guides you through configuration options for each of the available blocks. Collateral is also available to support the basic transceiver modes, including a generic characterization report, user guides, transceiver simulation models, and design kits for industry-standard PCB and layout simulation tools.
