Parade Applied sciences’ PS8780 four-lane bidirectional linear redriver restores high-speed indicators for lively cables, laptops, and PCs. It helps 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 as much as 2×40 Gbps symmetric or 120 Gbps uneven, TBT5 at 2×41.25 Gbps, and DP 2.1 UHBR20. It supplies full USB4, USB 3.2, and DP 2.1a energy administration, together with Superior Hyperlink Energy Administration (ALPM). Its low-power design and Fashionable Standby help lengthen battery life in cellular gadgets and scale back vitality use in lively cables.
The PS8780 extends USB4v2 indicators past the standard 1-m (3.3-ft) passive cable restrict whereas sustaining full efficiency. When paired with a USB4v2 retimer between the SoC (USB4v2 router) and the USB-C/USB4 connector, it additionally lengthens system PCB traces. Working from a 1.8 V provide, the system consumes 297 mW at 40 Gbps and simply 0.5 mW in standby. Its compact 28-pin, 2.8×4.4 mm QFN package deal fits space-constrained designs.
The PS8780 redriver is now sampling.
