About this Gig
Hello and Welcome!
High-speed Ethernet hardware is only as reliable as the signal integrity, PHY integration, and firmware controlling it. I specialize in developing Ethernet PCB solutions around the Realtek RTL8156B 2.5GbE USB Ethernet controller and RTL8221B 2.5G Ethernet PHY, with careful attention to high-speed differential routing, impedance control, power integrity, clocking, and hardware-software integration.
What I Will Provide:
- Custom RTL8156B/RTL8221B Ethernet PCB design
- Complete electronic schematic and component selection
- High-speed differential pair routing and impedance control
- Embedded firmware and hardware integration support
- Gerber, BOM, pick-and-place, and manufacturing files
Why Choose Me:
- Engineering-focused approach to high-speed Ethernet design
- Careful attention to signal integrity and PCB layout
- Hardware and firmware integration under one workflow
- Design documentation prepared for manufacturing
- Solutions tailored to your specifications and application

FAQ
What do you need to start my Ethernet PCB design?
I need your project requirements, target data rate, interface specifications, board dimensions, power requirements, and any existing schematics or reference designs.
Can you design a PCB using the RTL8156B and RTL8221B?
Yes, I can assist with Ethernet PCB architecture, component integration, schematic design, and layout based on your intended application and the devices' technical documentation.
Do you provide complete schematics and PCB layout?
Yes. Depending on your package, I can provide circuit schematics, PCB layout files, component placement, routing, and manufacturing documentation.
Will you provide Gerber files and a Bill of Materials (BOM)?
Yes. Manufacturing deliverables can include Gerber files, drill files, BOM, and pick-and-place files, depending on your selected package.
Do you provide embedded firmware development?
Yes, firmware development or integration support can be included where applicable. The scope depends on the target processor, operating system, available SDKs, and device programming requirements.
