Communication Interfaces
2.7.1
AT73C209-EK2 SPI
This board enables control of the AT73C209 via the SPI through the parallel port (J23).
If the user wants to program the AT73C209 with an external host, J15, J19 can be removed and the
AT73C209 driven directly.
The SPI Communication protocol is described in the AT73C209 data sheet. In any case, using the SPI
interface requires that a transformer be connected to J18.

On-Board Input Signal
On the AT73C209-EK2 there are several optional input signals. These inputs can be all driven or mixed
directly trough the internal amplifier.
2.8.1
Optical to Digital Converter (ODC)
The Optical to Digital Converter allows the user to connect an optical input line (J16) to the AT73C209
without any other necessary components (The plug type is Toslink).
2.8.1.1
ODC Set-Up
In order to connect the ODC with the I2S of the AT73C209, close G3, G4, G5 and G6 as shown in the

External Oscillator Configuration - Output Select
The external oscillator provides the sampling frequency for the Optical-to-I2S converter.
Two on-board configuration pads are available for configuring the 12.288 MHz oscillator (U6).
G7 pads provide Original Output Frequency (Frequency = 12.288 MHz) or Divided Output Frequency.
The divider is configured as (Frequency/2 = 6,144MHz).
G8 pads provide On/Off selection. When the oscillator is off, the output goes to high impedance state.
