ADSP-SC589 EZ-Board® Evaluation System Manual
20
The EZ-Board is configurable for either 12 outputs or 8 outputs and 4 inputs. Configuration is
performed through SoftConfig. The audio channels are available as single-ended RCA connectors J6
and J16. One output channel is also available on a 3.5mm headphone jack (J21).
For more information, refer to the audio example in the POST, which is included in the ADSP-SC589
Board Support Package.
2.11 S/PDIF Interface
The ADSP-SC589 processor has two built-in S/PDIF transmitters and receivers for digital audio
applications. The EZ-Board supports one S/PDIF interface and connects to the transmitter and
receiver through RCA and optical connectors J17, J15, J17, and J4.
The transmit and receive pins of the S/PDIF are connected to DAI pins through SoftConfig.
DAI0_PIN19 is connected to S/PDIF receive and DAI0_PIN20 is connected to S/PDIF transmit.

For more information, refer to the S/PDIF example in the POST, which is included in the ADSP-
SC589 Board Support Package.
2.12 Housekeeping ADC
The ADSP-SC589 processor provides eight housekeeping ADC inputs— HADC0_VIN0 through
HADC_VIN7. The EZ-Board connects HADC0_VIN0 to pin 1, HADC0_VIN1 to pin 4, and
HADC0_VIN2 to pin 5 of a six-position 0.1" header (P21). P21 has the 3.3V voltage domain on pin 1,
1.5V voltage domain on pin 3, and VDD_INT voltage domain on pin 6, allowing a jumper to connect
the voltage back to the processor.
HADC_VIN3 through HADC_VIN5 are connected to SMB connectors (J7, J8, and J8). HADC_VIN6
and HADC_VIN7 are connected to SMB connectors (J8 and J8) through a 1:1 buffer.
For more information, refer to the HADC example in the POST, which is included in the ADSP-
SC589 Board Support Package.
2.13 CAN Interface
The ADSP-SC589 processor has two CAN instances. Both are used by the EZ-Board.
The Controller Area Network 0 (CAN0) interface of the EZ-Board is connected to the NXP TJA1055
/3 enhanced fault-tolerant CAN transceiver. The transceiver is attached to the CAN0 port of the
ADSP-SC589 processor through an RJ-11 connector (J12). See CAN Connectors (J12–J13).
