General Description

The Physical Layer Controller with Scrambler (PLC-S) is a CMOS device which along with Physical Data Transmitter (PDT) and Physical Data Receiver (PDR) implements the Physical Layer Protocol (PHY) and portions of the Station Management (SMT) of the ANSI Fiber Distributed Data Interface (FDDI) standard.

The PLC-S, PDT and PDR are collectively known as the AmPHY.

PHY functions performed by the PLC-S include framing of data on symbol pair boundaries, the elasticity buffer function, the smoothing function, 4B/5B encoding and decoding of symbols, line state detection, the repeat filter function, and Stream Cipher Scrambling/Descrambling.
