1. Quad ProSLIC
The Quad ProSLIC software is an executable program
that allows control and monitoring of the ProSLIC. It
utilizes the USB port of a standard PC to communicate
to the Quad ProSLIC SPI port.
To install the software, insert the Silicon Laboratories
ProSLIC CD into the computer. The setup routine can
be invoked by running the setup.exe program in the root
directory of the CD.
Invoking the Quad ProSLIC GUI is achieved by
double-clicking the Quad ProSLIC GUI icon. Refer to
“AN265: Quad ProSLIC GUI User’s Guide” for more
information.
1.1. Si3241MB3/5/6-EVB Quad ProSLIC
The schematics for the Quad ProSLIC evaluation
daughtercard with the Si3205 line feed circuits are
shown in Figures 1 through 10. The schematic in
Figure 1 shows the Quad ProSLIC. Figure 2 shows the
serial control interface, PCM interface, and daisy chain
ports to the motherboard and connections. Figures 3
through 6 show the ac and dc sense paths and the line
feed ICs for the four channels. Figures 7 through 10
show basic protection circuitry. Depending on regulatory
requirements, this circuitry may need to be enhanced
for a given system architecture.
The
daughtercard is shown in Figure 11, which shows the
primary side component placement, while Figures 12
through 16 show the remainder of the layout.
The schematics for the Quad ProSLIC evaluation card
with the Si3203 or Si3206 linefeed circuits are shown in
Figures 17 through 24. This design uses the same
Quad ProSLIC device as well as the same interface to
the motherboard, but it uses a dual channel linefeed
circuit shown in Figures 19 and 20. The layout for this
daughtercard is shown in Figures 25 through 30.
Signal requirements for Quad ProSLIC operation are
PCLK (PCM clock), FS (frame sync), and Serial IO. The
Voice Motherboard uses a DSP to provide the Quad
ProSLIC the necessary PCLK and FS signals. Figures
31 through 42 show the design files of the Voice
Motherboard.

Rev. 1.1
The Voice Motherboard has been designed to directly
connect to an Audio Precision SIA-2322 Serial Interface
Adapter through the optional 15-pin d-connectors, P1
and P2.
See Table 1, “Audio Precision SIA-2322 DIP Switch
Setting,” on page 5. The Voice Motherboard has also
been designed to interface with a Wandel and
Goltermann PCM-4 through J4, J5, J6, and J7. See
Table 2 for PCM-4 settings. Tip and ring of the two-wire
analog interface are present at the RJ-11 connectors,
J1–J4, of the Quad ProSLIC daughtercard.
Power is connected to the Voice Motherboard at J11.
5 V is always required for the interface to the USB port.
This 5 V supply is then regulated down to 3.3 V for the
Si3241. VBHI, VBLO, and VBRNG are provided to the
Si3241 through the J11 connection. The Protection
Return connections on J12 should be connected to an
appropriate ground when performing any tip/ring fault
testing. This return is tied to signal ground on-board,
although it has a dedicated trace for high-current
conditions.

daisy-chained by stacking the cards. Stack up to four
cards by aligning JS1–JS6 and pressing them together.
The Quad ProSLIC software allows channel selection
for RAM and register manipulation.
1.2. Si3241MB3/5/6-EVB Quad ProSLIC
To prepare the Quad ProSLIC evaluation platform for
use, perform the following steps:
1. Set power supplies to 5 V, VBLO (–24 V), and VBHI
2. With these supplies off, connect them to J11,
3. If no VBRNG is used, also connect VBHI to VBRNG.
4. Connect the PC USB to J2.
5. Connect tip/ring from the RJ-11s to phone or
