The right power and timing solutions are very important for artificial intelligence (AI) accelerator cards. Generally, the 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 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® 7 clock generators support PCIe Gen 5/6 spread spectrum off(on), ~150fs RMS 12kHz to 20MHz clock gen integer, and four universal output pairs: LVPECL, LVDS, HCSL, or CMOS outputs. The RC19xxA is a PCIe Gen 5/6 fanout buffer with up to 24 outputs.
