Technical details and manufacturing context for Encoder/Decoder (ENDEC)

Definition
The Encoder/Decoder (ENDEC) is a critical functional block within a Physical Layer (PHY) chip responsible for the digital-to-analog and analog-to-digital conversion processes at the interface between a digital system and a physical transmission medium. It encodes outgoing digital data into a modulated analog signal suitable for the channel (e.g., Ethernet, optical fiber, RF) and decodes incoming analog signals back into digital data, handling line coding, modulation, clock recovery, and signal conditioning.
Working Principle
The encoder section takes parallel digital data, applies line coding (e.g., 8B/10B, 64B/66B) for DC balance and clock embedding, and drives a digital-to-analog converter (DAC) or a serializer to produce the transmitted analog waveform. The decoder section receives the analog signal, uses an analog-to-digital converter (ADC) or a clock and data recovery (CDR) circuit to sample it, decodes the line code, and outputs synchronized parallel digital data.
