Overview

The GW16-500 SerDes is a hard IP solution that delivers 500 Gbps of bi-directional throughput at ~ 1 pJ/bit across corners and is ideal for both ultra-short reach organic substrate on multi-chip-modules. It achieves low power through a combination of carefully chosen coding, efficient circuitry, and simple clocking and equalization schemes.

Features

  • 2-4x throughput at > 50 % energy savings compared to conventional SerDes.
  • No interposer required
  • Double-stackable
  • High pin-efficiency, low power, and low fixed latency
  • 208 Gbps/mm (single stack)
  • Supports up to 6dB channel insertion loss at 12.5 GHz
  • NRZ-like inter-symbol interference (ISI) performance
  • NRZ-like EMI, SSO and balance properties
  • Can be double-stacked to double throughput per mm of die edge.

Applications

  • USR links inside a shared package.
  • Processor-to-SerDes chiplet links.
  • Processor-to-Optics chiplet links.
  • Switch-to-switch links.
  • Links between heteorgenous chiplets.
