3 Description
•
AEC-Q100 Qualified for Automotive Applications:
The DP83TC811S-Q1 device is an IEEE 802.3bw-
compliant automotive PHYTER™ Ethernet physical
layer transceiver. It provides all physical layer
functions needed to transmit and receive data over
unshielded single twisted-pair cables. The device
provides xMII flexibility with support for standard MII,
RMII, RGMII, and SGMII MAC interfaces.

This device includes the Diagnostic Tool Kit,
providing an extensive list of real-time monitoring
tools, debug tools and test modes. Within the tool kit
is the first integrated electrostatic discharge (ESD)
monitoring tool. It is capable of counting ESD events
on both the xMII and MDI as well as providing real-
time monitoring through the use of a programmable
interrupt. Additionally, the DP83TC811S-Q1 includes
a pseudo random binary sequence (PRBS) frame
generation tool, which is fully compatible with internal
loopbacks, to transmit and receive data without the
use of a MAC. The DP83TC811S-Q1 is housed in a
6.00-mm × 6.00-mm, 36-pin VQFN wettable flank
package.
