It is common that these PHY portions are integrated with the media access control (MAC) layer in System-on-a-chip (SOC) implementations. A PHY device typically includes both Physical Coding Sublayer (PCS) and Physical Medium Dependent (PMD) layer functionality.ApplicationsWireless LAN or Wi-Fi: The PHY portion consists of the RF, mixed-signal and analog portions, that are often called transceivers, and the digital baseband portion that use digital signal processor (DSP) and communication algorithm processing, including channel codes.

JSTOR (May 2013) (Learn how and when to remove this template message) RTL8201 Ethernet PHY chipPHY is an abbreviation for the physical layer of the OSI model and refers to the circuitry required to implement physical layer functions.A PHY connects a link layer device (often called MAC as an acronym for medium access control) to a physical medium such as an optical fiber or copper cable.
