Si3225PPT-EVB Dual ProSLIC Evaluation
Platform Setup
To prepare the Dual ProSLIC evaluation platform for
use, perform the following steps:
1. Set power supplies to 3.3 V, 5 V, –24 V, and –75 V.
2. Connect ringing source to J5.
3. With these supplies off, connect them to J2, J3, and J4
4. Connect the PC’s parallel port (LPT1) to P1 (or J1) using a
5. Select the on-board PCM clock source or select external
6. TIP/RING connection can be made from the RJ-11s to a
7. Invoke the ProSLIC LINC software.
