3 Description

The DP83TC811R-Q1 device is an IEEE 802.3bwcompliant

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, and RGMII 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 realtime

monitoring through the use of a programmable

interrupt. Additionally, the DP83TC811R-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 DP83TC811R-Q1 is housed in a

6.00-mm × 6.00-mm, 36-pin VQFN wettable flank

package.
