PS8778
A bidirectional 4-lane linear redriver that reconditions USB and DP signals, compliant with USB4, USB3.2 and DP.a. Supports USB4 Gen3 speeds up to 20Gbps per lane and DP UHBR20, ensuring high-speed signal quality for USB-C topologies. Applies to both host and device sides, including USB-C active cables, with signal compensation adjustable via I2C for its operating mode, EQ and DC gain. Supports lane and P/N polarity swapping, low power consumption and full power management for USB4, USB3.2 and DP.a links.
It detects sideband signals from DP mode (AUX) and Thunderbolt3/USB4 mode (SBTX/RX) to optimize configuration and power saving modes. It operates from a 1.8V power supply and is housed in a compact QFN package. It also features an automatic power saving mode, which goes into low power mode when the channel is idle and resumes normal functionality when a signal is detected.
