12Gbps multi-channel BERT board reference design

TIDA-00426

Overview

This reference design is a 12Gbps low-cost bit error tester (BERT) that generates and checks up to 8 channels of pseudo-random binary sequences (PRBS). This proven design provides a convenient way to generate multi-lane high-speed serial bit streams up to 12Gbps and inspect the incoming serial bit stream for bit errors. This design can be used as a handheld BERT to evaluate the signal integrity and bit error performance of high-speed subsystems.

characteristic

● 8 pattern generation channels
● 8 pattern check channels
● Optional external reference clock input
●Onboard USB-to-I2C for easy device programming
● Status display LED

When the FSMC of STM32 is connected to an external 16-bit Nand, is the output address or command 16 bits?
When the FSMC of STM32F103VC is connected to an external 16-bit Nand, should the address or command written by the CPU to the Address section or Command section be 16 bits or 8 bits? Is the actual out
What is the function of serpentine routing on FPC board?
Any trace on the FPC will cause delay to the signal when passing a high-frequency signal. The main function of the serpentine trace is to compensate for the smaller delay parts of the "same group of r
Please advise on reading and writing USB host computer
I have a USB device, but I don't know the port. How can I read and write data? I use createfile, writefile, and readfile to open the USB device. There is no port in the USB path. The handle is opened
[FPGA (cyclone4) second issue] Timing and simulation learning - pipeline LUT multiplier
[color=#000][font=Tahoma][size=3]Pipeline operation can be said to be the privilege of Verilog HDL language. It is difficult to implement pipeline operation in sequential operation such as C language.
