AMCC S3045 Manual

SONET/SDH OC-48 TO OC-12 MUX/DEMUX EVALUATION BOARD
SONET/SDH OC-48 TO OC-12 MUX/DEMUX EVALUATION BOARD
DESCRIPTION
The S3045 Evaluation Board provides a flexible platform for verifying the operation of the S3045 with a SONET
tester. This user's manual provides information on the board contents.
Figure 1 shows the outline of the S3045 Evaluation Board. In Figure 2, the block diagram of how the S3045
Evaluation Board should be connected to the test equipment for SONET/SDH testing is shown. The four
possible test configurations are:
1.Use both the input/output on board clock recovery devices (S3040 #1, #2).
2.Use the input on board clock recovery device (S3040 #1).
3.Use the output on board clock recovery device (S3040 #2).
4.Do not use any of the on board clock recovery devices.
Figures 4-7, show the wiring connections for these four test setups.
The SONET network tester compares the received data with the transmitted data to determine whether an error
has occurred. The SONET tester can also demonstrate the SONET protocol features of the chipset. In addition,
most SONET testers should be able to manipulate any bits being transmitted to the S3045 test board to verify
the operation of SONET overhead and alarm functionality.
Required Parts:
The tests can be conducted using a SONET Tester and the Unit Under Test ( the S3045 Evaluation Board). The
following is a parts list of the items that will be needed.
1.Power cable between the power source and the S3045.
2.S3045 Test Board.
3.One 5 volt power supply (Current rating 2 Amps).
4.SONET/SDH network tester.
5.50 Ohm SMA terminated test cables.
6.Optional: –5.2V DC supply for VBB as required for SONET termination pulldowns.
Power Connections
Terminal posts are provided at the top edge of the board for VCC (+5V), and GND. The required +5V power
supply connected to the board provides the 5 volts for the S3040's. The board contains two power regulators
with one providing the 3.3 volts for the S3045, and the other supplying the 3.3 volts for the S3041 and S3042.
Figure 3 demonstrates the input and output LVPECL waveforms that the S3045 Evaluation Board will output.
(Note that in the final design of the S3045 Evaluation Board, the regulator providing 3.0V and 4.1V will be
modified to supply 3.3V by replacing R2 and R12.)
