Functional Descriptions
This section provides detailed information about how the VSC8601 device works, what
configurations and operational features are available, and how to test its functions. It
includes descriptions of the various device interfaces and how to set them up.
Interface and Media
The VSC8601 device operates with the interface and media shown in the following table
and illustration.

RGMII to Cat5 Block Diagram
MAC Interface
The VSC8601 supports RGMII versions 1.3 and 2.0 (2.5 V, 3.3 V) MAC interface.
MAC Resistor Calibration
To simplify board design, the VSC8601 MAC interface uses SimpliPIN
self-calibrate to a desired impedance characteristic to eliminate the need for series
termination resistors. By default, these RX output pins calibrate to 50 Ω. In addition,
MII Register 19E, bits 15:14 can be used to select different target impedances. For
more information, see
RGMII MAC Interface Mode
The RGMII interface can support all three speeds (10 Mbps, 100 Mbps, and 1000 Mbps)
and is used as an interface to an RGMII-compatible MAC.
