Diodes Incorporated PI3EQX32908 8-Channel Linear ReDrivers™

Diodes Incorporated PI3EQX32908 8-Channel Linear ReDrivers™ are high-performance, multi-data rate device compliant with PCIe 5.0, SAS4, and CXL protocols. The PI3EQX32908 ReDrivers meet the standby mode requirements outlined by Microsoft® Corporation and deliver high linearity and ultra-low jitter characteristics. These ReDrivers support eight 100Ω differential CML data I/Os, the device extends signals across data pathways on the user's platform. The PI3EQX32908E ReDrivers support I2C master mode for external EEPROM and up to sixteen masters connected in a daisy chain.

The PI3EQX32908 ReDrivers™ provide programmable linear equalization, output swing, and flat gain. Equalization is controlled by either a pin-strapping option or I2C control and optimizes performance over various physical media by reducing intersymbol interference. These devices extend PCB trace lengths while minimizing cost/power consumption and deliver low latency. Operating from a 3.3V supply voltage, the PI3EQX32908 ReDrivers operate over a temperature range of -40°C to 85°C and are packaged in a WQFN-62 package. Applications include networking, enterprise, servers, and storage.
