2. Configuring the Si-LINK
The Si-LINK motherboard is used to interface the
Si3050 to a PC or other audio system for easy
evaluation. It uses an FPGA to translate the parallel port
interface to either SPI/PCM, SPI-only, or GCI to
communicate with the Si3050.
When in SPI/PCM mode, the PCM audio data and SPI
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.
By selecting SPI-only operation, the PC is still used to
control the DAA through the SPI bus, but the PCM
By changing the jumper configuration prior to powering
the board, the mode of the board can be set according
to Tables 1–3.
JP10 is the sixth jumper on the Si-LINK motherboard.
Moving this jumper to the INT position routes pin 9 of
the Si3050 to the Si-LINK motherboard. When the
jumper is in the AOUT position, this signal is routed to
the optional call progress speaker system, which is not
populated by default on the evaluation platform. Refer to
the AOUT PWM circuit in the Si3050 data sheet for
values used to populate this circuit.
Table 1. PCM or GCI Highway Mode Selection
audio data is routed from an external source. This
external source may be an Audio Precision system
using the P1 and P2 headers or a PCM highway using
the BNC connectors, J5–J8 (not populated).
To evaluate the Si3050’s operation with the GCI
interface, the PC may be used to send the audio data
and control. The FPGA performs the necessary

translation to communicate to the Si3050 in this mode.
The fourth mode of operation is the pass-thru mode. In
this mode, the FPGA is only used to route the GCI bus
to the Audio Precision or BNC headers on the Si-LINK
board. In this mode, a PC is not required to control the
evaluation platform.

rising edge of RESET.
