AMD 4th-Gen EPYC (Genoa) Power & Timing System

Overview

Renesas provided a complete power and timing system for the AMD Genoa platform, including our latest third-generation common footprint digital multiphase SVI3 power solutions and PCIe Gen 5/6 clock solutions. Renesas' third-generation core power solutions could work with the latest trans-inductor voltage regulator (TLVR) technologies to provide industry-best power performance to CPUs; not only could this help customers easily pass CPU testing specs, but it could also help eliminate some bulk capacitors and save PCB space and cost. Along with core power solutions, Renesas also provides a DDR5 power management IC (PMIC), which enables onboard mount DDR5 support. With these power and timing solutions, Renesas becomes one of the most important players in the server market and is ready to support all our customers.

System Benefits​:

  • Enabled common footprint SVI3 total power solution
  • PCIe Gen 5/6 full timing solution
  • DDR5 PMIC compliant with I3C interface
