Configuring the Si30xxPPT-EVB
The S30xxPPT-EVB is used to interface the Si30xx
chipset to a PC or other audio system for easy
evaluation. It uses an FPGA to translate the parallel port
interface to the SSI bus to communicate to the Si30xx.
The audio data and control data are communicated from
the controlling PC using the aforementioned software.
This mode allows the user to evaluate the DAA without
any lab equipment other than a PC.
When in mode 0, the negative edge of FSYNC indicates
the starting of the frame, and FSYNC is low until the end
of data transfer. By selecting mode 1 operation, the
rising edge of FSYNC indicates the start of the frame,
but is only high for one cycle. To evaluate the Si30xx’s
multiple device operation, chain the slave boards with
JP3 and JP4 set to mode 2. See Table 1 for a
description of these operating modes.

Preliminary Rev. 1.0
The Si30xxPPT-EVB has the ability to interface in two
different modes of the SSI bus: 5-bit address space
operation is used for the Si3034/35/44, and 7-bit
address space operation is used for the Si3056. Table 2
shows how to configure the Si30xxPPT-EVB to operate
in a desired SSI operational mode.
