Repeater IC boosts signal quality of high-speed PCIe 4.0 interfaces
The IC regenerates signals to boost the signal quality of high-speed interfaces and is claimed to be the industry’s first available ReDriver to support PCIe 4.0 while being backward-compatible with PCIe 3.0/2.0/1.0. Using equalization, pre-emphasis, and other technologies, a single ReDriver can adjust and correct for known channel losses at the transmitter and restore signal integrity at the receiver. This enables reliable communications with low bit error rates (BER).
The PI3EQX16904GL supports four 100Ω differential current mode logic (CML) data I/Os and extends the signals across other distant data pathways on the user’s platform. Linear ReDrivers are commonly used to achieve PCB trace extension while minimizing cost and power consumption. They can also deliver lower latency. Requiring a supply voltage of 3.3V ±0.3V, the 9×3.5mm device is able to operate over an industrial temperature range of -40 to +85˚C.
