The PI3EQX32904Q from Diodes Incorporated is a four-channel automotive linear ReDriver designed to support high-speed PCIe 5.0, SAS4, and CXL interfaces. It complies with Modern Standby mode requirements while delivering high linearity and ultra-low jitter to ensure reliable signal integrity in demanding automotive environments.
The device provides programmable linear equalization, output linearity, and flat gain, allowing designers to fine-tune performance for optimal signal conditioning. Its I2C-controlled equalization reduces intersymbol interference across a wide range of physical media, enabling consistent performance over varying channel conditions.
By extending PCB trace lengths, the device helps reduce system cost and overall power consumption while maintaining low-latency operation. Operating from a 3.3V supply, the PI3EQX32904Q supports the industrial temperature range of -40ºC to +85ºC. It is available in the compact W-QFN3063-46 (ZR46) package.
The PI3EQX32904Q is a 32Gbps high-performance linear ReDriver supporting Modern Standby mode for reduced power consumption. It supports PCIe 5.0, SAS4, and CXL protocols and consumes less than 5mW power when the system is in deep standby mode. The PI3EQX32904Q has I2C selectable device programming with automatic receiver detection and low-power mode support. It is suitable for smart cockpits, ADAS, infotainment and clusters.
