Hello
Receently, I am reviewing and confirming the contexts of FPD Link such as under the image.
While reviewing contexts of FPD Link, I have a question about that equation between bit rate (Gbps) and bandwidth (GHz).
What is the detailed principle of getting that equation such as GHz = 1/2 Gbps ?
Why the bandwidth is half of the bit rate ? Is it related with NRZ ?
Thank u.
GHz and Gbps are two different ways to describe the same waveform.
In FPD-Link I, the clock signal actually is seven times slower than the data signals, and the receiver recovers the higher clock with a PLL. See section 4 of AN-1032: An Introduction to FPD-Link.
Thank u for answering.
It was helpful to understand using NRZ signaling.
Below contents are mentioned which I understand again.
In the below example picture, the bit rate 10 bps and the frequency 5 hz which is frequency in the case highest transition rate signal.
And that frequency is Nyquist frequency.
