Webb21 dec. 2024 · 14 人赞同了该回答. phy指的是协议物理层. serdes指的是串并转换器. 在很多串型传输协议中phy通常是由serdes实现的. 所以通常大家提phy和serdes通常指的是同一个东西. 但是一个serdes design通常会同时支持多种协议，在不同的应用中会包上不同的wrapper以支持不同协议 ... Before a register access, PHY devices generally require a preamble of 32 ones to be sent by the MAC on the MDIO line. The access consists of 16 control bits, followed by 16 data bits. The control bits consist of 2 start bits, 2 access type bits (read or write), the PHY address (5 bits), the register address (5 bits), and 2 "turnaround" bits.
