32-Gbps redriver improves in-vehicle connectivity
The PI3EQX32904Q automotive four-channel redriver from Diodes optimizes signal integrity for smart cockpits combining ADAS, infotainment systems, and instrument clusters into a single unit. Designed for GPU+CPU SoCs, it supports data rates up to 32 Gbps for high-speed PCIe 5.0, SAS-4, and CXL interfaces.
The linear redriver is rate and coding agnostic without interfering with link setup. Four independent differential channels allow configuration of receiver equalization, output swing, and flat gain through an I2C interface. Designers can tune signal performance across various physical media and system configurations with minimal firmware overhead. In addition, the ability to extend PCB trace lengths helps reduce intersymbol interference.
Built using a 0.13-µm SiGe BiCMOS process, the PI3EQX32904Q delivers robust data transmission with high linearity and low jitter. It operates from a 3.3-V supply across a -40°C to +85°C temperature range. The device complies with Modern Standby (S0 Low Power Idle) requirements, consuming less than 5 mW in deep standby while maintaining readiness for rapid wakeup.
Prices for the PI3EQX32904Q start at $4.84 each in 1000-piece quantities.
