Capstone Project 1: High-Speed Channel Design
Design a 10 Gbps serial channel that meets the eye mask specification. Apply everything you have learned about transmission lines, reflections, crosstalk, and equalization.
Project Brief
Objective
Design a 10 Gbps (100 ps UI) high-speed serial channel from transmitter to receiver. The channel must pass an eye mask test with adequate margin for manufacturing variation.
| Parameter | Specification | Unit |
|---|---|---|
| Data Rate | 10 | Gbps |
| Unit Interval (UI) | 100 | ps |
| Min Eye Height | 120 | mV |
| Min Eye Width | 0.6 | UI |
| Max Jitter (Tj) | 0.35 | UI |
| Target BER | 1e-12 | -- |
| Max Insertion Loss @ 5GHz | -20 | dB |
| Max Crosstalk | -30 | dB |
Step 1: Channel Setup
Configure the physical channel parameters. These choices determine loss, impedance, and delay.
Configure parameters and click Preview.
Step 2: Reflection Fix
Select the termination strategy to minimize reflections on your channel.
Select termination and analyze.
Step 3: Eye Improvement with Equalization
Configure TX and RX equalization to open the eye diagram.
-2.0 dB
-4.0 dB
6 dB
Configure EQ and preview the eye.
Step 4: Crosstalk Reduction
Adjust spacing and shielding to meet crosstalk requirements.
Configure spacing and analyze.
Step 5: Compliance Check
Run the full compliance check against all specifications.
