have as linear a power supply as possible, as little electronic noise as possible (jitter) with the most accurately timed data stream as possible.
Music servers do not pass ones and zeros through wire, they switch on and off either power or light or whatever means the signal is transferred it is done by switching between on and off.
The less electronic noise the more effectual the measuring, reading, transferring of the encoded data is. It’s an analog means of transferring data as a series of nulls and ones (on and off) which can be deciphered into logical and meaningful information.
To analogize, jitter or electrical noise mixed with the actual datastream can cause incorrect bits in the data. Without getting into things like electrical noise and mitigation; it’s not unlike two people giving instructions when only one of them is correct, and you can’t tell them apart.
Field-Programmable Gate Arrays is a bit like having a configurable integrated circuit. It's not set in stone like an IC is, where the function is set. They are often used to prototype and test before the IC is created from the FPGA prototype.
