Overview
The DS80PCI102SQ/NOPB, produced by Texas Instruments, is a 2.5/5.0/8.0-Gbps 1-lane PCI Express redriver designed to enhance the reach of PCI-Express serial links in board-to-board or cable interconnects. This low-power, 1-lane repeater features 4-stage input equalization and an output de-emphasis driver, making it ideal for x1 PCI-Express configurations. The device automatically detects and adapts to Gen-1, Gen-2, and Gen-3 data rates, facilitating easy system upgrades.
