Overview

The GW28-125 SerDes is a hard IP solution that delivers 125 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

  • No interposer required.
  • Double-stackable.
  • High pin-efficiency, low power, and low fixed latency.
  • 86 Gbps/mm bidrectional data throughput.
  • Supports up to 3 dB channel insertion loss at 12.5 GHz.
  • NRZ-like inter-symbol interference (ISI) performation.
  • NRZ-like EMI, SSO and balance properties.

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.
