Overview

Description

The right power and timing solutions are very important for Artificial Intelligence (AI) accelerator cards. Generally, current is above 50A and core power is below 1V and is suitable for a multiphase power supply. AI accelerator cards utilize a PCIe interface with many channels so a PCIe clock generator and clock buffer are needed. Renesas delivers leading power solutions and clocking solutions for AI acceleration. High-efficiency power ICs save PCB space and mitigate heat radiation for kW level power consumption. High-performance programmable VersaClock® 6E clock generators support PCIe Gen1-5 spread spectrum off(on), <0.5ps RMS phase jitter, 4 universal outputs pairs: LVPECL, LVDS, HCSL, or 8 LVCMOS outputs. The 9QXL2001 is a 20-output DB2000QL PCIe clock buffer.
