Redriver strengthens USB4v2 and DP 2.1a signals
Parade Technologies’ PS8780 four-lane bidirectional linear redriver restores high-speed signals for active cables, laptops, and PCs. It supports USB4v2 Gen 4, Thunderbolt 5, and DisplayPort 2.1 Alt Mode, and is pin-compatible with the PS8778 Gen 3 redriver.
The redriver delivers USB4v2 at up to 2×40 Gbps symmetric or 120 Gbps asymmetric, TBT5 at 2×41.25 Gbps, and DP 2.1 UHBR20. It provides full USB4, USB 3.2, and DP 2.1a power management, including Advanced Link Power Management (ALPM). Its low-power design and Modern Standby support extend battery life in mobile devices and reduce energy use in active cables.
The PS8780 extends USB4v2 signals beyond the typical 1-m (3.3-ft) passive cable limit while maintaining full performance. When paired with a USB4v2 retimer between the SoC (USB4v2 router) and the USB-C/USB4 connector, it also lengthens system PCB traces. Operating from a 1.8 V supply, the device consumes 297 mW at 40 Gbps and just 0.5 mW in standby. Its compact 28-pin, 2.8×4.4 mm QFN package suits space-constrained designs.
The PS8780 redriver is now sampling.
