Introduction & Design Goals

Overview

This document provides hardware design guidelines for the Realtek AmebaPro2 platform.

It serves as a reference for schematic design, PCB layout implementation, and hardware review prior to mass production.

The goal of this guide is to help hardware engineers:

  • Design stable and reliable boards based on AmebaPro2

  • Reduce board bring-up time

  • Avoid common schematic and layout mistakes

  • Improve EMC and signal integrity performance

  • Increase first-pass design success rate

Target Audience

This guide is intended for:

  • Hardware design engineers

  • PCB layout engineers

  • System integrators

  • Technical reviewers performing schematic or layout checks

It assumes readers have basic knowledge of:

  • Power supply design

  • High-speed signal routing

  • PCB stack-up and impedance control

  • Embedded system development

Hardware Design Philosophy

The AmebaPro2 platform integrates high-speed interfaces, multimedia inputs, and switching power circuits into a compact system-on-chip (SoC).

Proper hardware implementation is critical to ensure:

  • Stable boot behavior

  • Reliable firmware download and debug access

  • Clean and stable power delivery

  • Controlled EMI emission

  • Robust high-speed communication performance

This guide separates design recommendations into two major phases:

  1. Schematic Design Guidelines

    Focused on correct circuit implementation, signal configuration, and power architecture.

  2. PCB Layout Guidelines

    Focused on component placement, routing strategy, grounding, impedance control, and noise reduction.

Design Flow Overview

A recommended hardware development flow is:

  1. Review the datasheet and reference design.

  2. Complete schematic design following this guide.

  3. Perform schematic self-check using the checklist.

  4. Implement PCB layout according to the layout guidelines.

  5. Conduct layout review (power, high-speed signals, grounding).

  6. Perform board bring-up and validation testing.

Following this structured flow significantly reduces hardware iteration cycles and improves overall product reliability.

Note

The EVB schematic is optimized for the evaluation board design only. It should be used as a reference example. Actual product designs may require additional considerations. Do not directly copy the EVB schematic without proper review and validation.
