3 Description
The DP83TC811-Q1 device is an IEEE 802.3bwcompliant
automotive PHYTER™ Ethernet physical
layer transceiver. The device 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. The tool 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 DP83TC811-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 DP83TC811-Q1 is housed in
a 6.00-mm × 6.00-mm, 36-pin VQFN wettable flank
package.
