Diodes Incorporated PI3EQX32904Q Automotive PCIe 5.0 ReDriver™
Diodes Incorporated PI3EQX32904Q Automotive PCIe 5.0 ReDriver™ is a low-power, high-performance 32Gbps 4-channel ReDriver. This Diodes Inc. ReDriver provides programmable equalization, swing, and flat-gain I2C control to optimize performance across a variety of physical media by reducing intersymbol interference. The device supports two 100Ω differential CML data I/Os between the Protocol ASIC to a switch fabric, over cable, or to extend the signals across other distant data pathways on the user’s platform. The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver. A low-level input signal detection and output squelch function is provided for each channel. Each channel operates fully independently. The channels’ input signal level determines whether the output is active. The PI3EQX32904Q automotive PCIe 5.0 ReDriver also includes an adaptive power management feature to maximize battery life for power-sensitive consumer devices.
