10 HDMI 

The Arty Z7 contains two unbuffered HDMI ports: one source port J11 (output), and one sink 
port J10 (input). Both ports use HDMI type-A receptacles with the data and clock signals 
terminated and connected directly to the Zynq PL.  

Both HDMI and DVI systems use the same TMDS signaling standard, directly supported by 
Zynq PL's user I/O infrastructure. Also, HDMI sources are backward compatible with DVI 
sinks, and vice versa. Thus, simple passive adaptors (available at most electronics stores) can 
be used to drive a DVI monitor or accept a DVI input. The HDMI receptacle only includes 
digital signals, so only DVI-D mode is possible.  

The 19-pin HDMI connectors include three differential data channels, one differential clock 
channel five GND connections, a one-wire Consumer Electronics Control (CEC) bus, a two-
wire Display Data Channel (DDC) bus that is essentially an I2C bus, a Hot Plug Detect (HPD) 
signal, a 5V signal capable of delivering up to 50mA, and one reserved (RES) pin. All non-
power signals are wired to the Zynq PL with the exception of RES.

10.1 TMDS Signals 

HDMI/DVI is a high-speed digital video stream interface using transition-minimized 
differential signaling (TMDS). To make proper use of either of the HDMI ports, a standard-
compliant transmitter or receiver needs to be implemented in the Zynq PL. The 
implementation details are outside the scope of this manual. Check out the vivado-library IP 
Core repository on the 

Digilent github

 for ready-to-use reference IP.
