Figure 14. ZYBO GPIO.
The high-efficiency LEDs are anode-connected to the Zynq via 330-ohm resistors, so they will turn on when a logic
high voltage is applied to their respective I/O pin. Additional LEDs that are not user-accessible indicate power-on,
FPGA programming status, and USB and Ethernet port status.
The LED and two pushbuttons attached directly to the PS are accessed using the Zynq GPIO controller. This core is
described in full in Chapter 14 of the Zynq Technical Reference Manual.
14 Audio
An Analog Devices SSM2603 Audio Codec provides integrated digital audio processing to the Zynq-7000 AP SoC. It
allows for stereo record and playback at sample rates from 8 kHz to 96 kHz.
On the analog side, the codec connects to three 3.5 mm standard audio jacks. There are two inputs: a mono
microphone and a stereo line in. There is one stereo output, the headphone jack. Analog power is provided by a
dedicated linear power supply (IC6).
