5.2 10-Bit PHY Interface
The 10-bit PHY interface directly couples to any external physical layer
device that complies with the IEEE 802.3z or the 10-bit ANSI X3.230
interface standards.
5.2.1 External Physical Layer Devices
In a typical configuration, the controller is connected to an external
Serializer/Deserializer (SerDes) Integrated circuit, as shown in
Figure 5.1. A list of SerDes devices whose specifications are compatible
with and can directly connect to the controller is shown in Table 5.1.
