1. Overview

Stratix® 10 devices offer up to 144 transceivers with integrated advanced high-speed analog signal conditioning and clock data recovery circuits for chip-to-chip, chip-to-module, and backplane applications.

The Stratix® 10 devices contain a combination of GX, GXT, or GXE channels, in addition to the hardened IP blocks for PCI Express* and Ethernet applications.

The Stratix® 10 device introduces several transceiver tile variants to support a wide variety of protocol implementations. These transceiver tile variants are L-tiles, H-tiles, and E-tiles. This user guide describes both the L- and H-tile transceivers. For Stratix® 10 devices that only contain E-tiles, refer to the E-Tile Transceiver PHY User Guide.
