Hardware Guide
Hardware Configuration
The ADV7513 HDMI transmitter is integrated on-board the DE10-Nano. The FPGA fabric drives the ADV7513 with digital video and audio data, transmitting it over HDMI.
The ADV7513 is configured over I²C. The ARM Cortex-A9 processor in the Cyclone V SoC acts as the I²C master.
Power Supply
The ADV7513 is powered directly from the evaluation board’s on-board power supply. No external power supply is required for the HDMI transmitter.
Functional Description
Video Interface Configuration
The DE10-Nano reference design uses:
16-bit YCbCr 4:2:2 interface
Separate synchronization signals (HSYNC, VSYNC, DE)
Pixel clock: up to 148.5 MHz (1920×1080 @ 60 Hz)
The ADV7513 supports pixel clocks up to 165 MHz, covering all resolutions up to 1080p and UXGA.
Audio Interface Configuration
The DE10-Nano reference design uses:
Single-bit S/PDIF interface
No audio master clock required (clock recovered from S/PDIF bitstream)
Sample rates: 32 kHz, 44.1 kHz, 48 kHz
16-bit or 24-bit audio samples
Under Linux, the ADV7513 audio is exposed as an ALSA audio device through the ASoC framework. The following DAI formats are supported:
Format |
Description |
|---|---|
|
Standard I²S (up to 8 channels, up to 192 kHz) |
|
S/PDIF (stereo LPCM or IEC 61937 compressed) |
Software Guide
Linux Software
Under Linux, the ADV7513 is supported by the adv7511 DRM bridge
driver (drivers/gpu/drm/bridge/adv7511/). The driver uses the
"adi,adv7513" compatible string and is otherwise identical to the ADV7511
driver, with the exception that pixel clocks above 165 MHz are rejected.
The driver implements the DRM bridge interface and exposes:
HPD (Hot Plug Detect) monitoring
EDID read from the HDMI sink via DDC (I²C)
HDCP v1.4 support
CEC controller (via separate CEC framework driver)
The framebuffer is provided by the AXI HDMI driver (AXI HDMI HDL), which uses the AXI-DMAC to stream pixel data from memory to the ADV7513.
Relevant Linux drivers:
ADV7511 (supports ADV7511, ADV7511W, ADV7513, ADV7533, ADV7535)
