1. Introduction
The ProSLIC Si321x evaluation platform is a modular
system consisting of a generic motherboard and one or
more Si321x device-specific daughter cards. Using the
EVB hardware and ProSLIC LINC™ software, one can
easily configure, control, and monitor Si321x operation.
Up to eight Si321x daughter cards may be stacked
vertically and accessed using uniquely-assigned
timeslots on the common PCM interface and the SPI in
daisy-chain mode.
Motherboard hardware schematics are found in Figures
25, 26, and 27.
All power and signal connections are made to the
motherboard as described in Table 2.
Signal requirements for ProSLIC operation are PCLK,
FS, and Serial IO. The ProSLIC motherboard has a
local oscillator with a programmable logic device to
provide the ProSLIC PCLK FS signals. The DIP switch
(S2) sets the PCLK frequency and controls the FS
enable. See Table 3 for S2 settings. Factory default
setting is for a 2.048 MHz PCLK with F5 enabled. JP3
and JP4 select this internal clock source or an external
PCM clock source. The ProSLIC motherboard has been
designed to directly connect to an Audio Precision SIA-
2322 Serial Interface Adapter through the 15 pin d-
connectors, P2 and P3 (not installed). See Table 5 for
the Audio Precision settings. The ProSLIC evaluation
board has also been designed to interface with a
Wandel and Goltermann PCM-4 through J8, J9, J10,
and J11 (not installed). See Table 6 for PCM-4 settings.
A header, J5 (not installed), allows access to the
ProSLIC’s PCM signals for connection to other PCM
testing devices or an actual telephone system PCM
bus. TIP and RING of the two wire analog interface is
present at the RJ-11 connector, J1.
The ProSLIC evaluation board is voltage-programmable
with specific jumper settings. JP1 selects 3 or 5 V
ProSLIC operation. JP2 selects 3 or 5 V PCM source
level compatibility. These should be placed on the
expected setting. Table 4 shows a summary of JP1–4
settings.
Power is connected to the ProSLIC at J3 and J4, and
supply connections are summarized in Table 1. The 5 V
is always required for the buffers, U2 and U3, to
interface to the parallel port. The ProSLIC can be
powered from 5 V or 3 V with the placement of a jumper
on JP1. The Protection Return connections on J6 are to
be connected to an appropriate ground for TIP/RING
fault testing. This return is tied to signal ground on
board, although it has a dedicated trace for high-current
conditions. Serial control of the ProSLIC is achieved by
toggling select bits of a standard parallel port. The
parallel port connection is available at P1 and J1.
The ProSLIC card can be daisy-chained by simply
stacking the cards. Stack up to eight cards by aligning
JS1–JS6 and pressing together. The ProSLIC LINC
Software allows channel-specific commands by clicking
the
Daisy Chain
button.
1.1. ProSLIC LINC evaluation software
The ProSLIC LINC software is an executable program
that allows control and monitoring of the ProSLIC. It
utilizes the primary LPT port of a standard PC to
communicate to the ProSLIC’s 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 ProSLIC LINC is achieved by double
clicking the ProSLIC LINC icon. Refer to the ProSLIC
LINC User Guide for software operation.

1.3. ProSLIC Evaluation Board Setup
To prepare the ProSLIC evaluation board for use,
perform the following steps:
1. Set power supplies to 3.3 V, 5 V, and 12 V.
2. With these supplies off, connect them to J3 and J4
corresponding to the silk screen designators.
3. Connect the PC’s parallel port (LPT1) to P1 (or J1)
using a 25-pin D male-to-male cable.
4. Select the on-board PCM clock source, or select an
external PCM source, and connect an Audio
Precision SIA-2322 to P2 and P3 or a Wandel and
Goltermann PCM-4 to J8, J9, J10, and J11.
5. TIP/RING connection can be made from the RJ-11 to
a phone or telephony test equipment.
6. Invoke the ProSLIC LINC software.
7. Turn the power supplies on and press the ProSLIC
evaluation board reset button (S1).
8. Click the “Reinitialize” button in the ProSLIC LINC
software panel
The ProSLIC is now ready to perform its linecard
function.
Notes:
1.
All three GND connection points are electrically
connected on the board.
2.
+3.3 V is only necessary if that is the desired VDD for
operation. Si321x chooses +3.3 V or +5 V based on
the SP1 of the motherboard (see schematic).
3.
This may be changed based on application-specific
circuits. Consult the dc-dc converter spreadsheet for
other possible values.
