The HDMI Audio EI3 EZ-Extender is a separately sold daughter board that plugs onto the expansion interface III of the EZ-Board evaluation platform. The daughter board aids the design and prototyping phases of HDMI HD audio decode/encode applications. The board extends the capabilities of the evaluation system by providing a connection to three analog audio codecs along with an HDMI transmitter/receiver.
The HDMI Audio EI3 EZ-Extender’s analog audio interface is comprised of three Analog Devices AD1939 multichannel audio codecs. The AD1939 is a high performance, single-chip codec featuring four analog-to-digital converters (ADCs) for audio input and eight digital-to-analog converters (DACs) for audio output. This translates to twelve channels of audio in and twenty four channels of audio out. The codec/extender can input and output data at a sample rate of up to 192 kHz on all channels.
This HDMI Audio EI3 EZ-Extender connects with the Expansion Interface 3 (EI3) which gives the user more available signals on the interface connectors and a reduction in size over the previous EI2 specification. Software examples are provided to demonstrate the functionality of the devices on the Extender Board.
