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.
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.
