• Manufacturer Part Number: S3045
• Description: S3045 Sonet/sdh Oc-48 to Oc-12 Mux/demux Evaluation Board
• Manufacturer: AMCC (Applied Micro Circuits Corp)

Figure 2. Test Setup (Differential Version Shown)
VBB should be –5.2V for tester outputs that require DC pulldown for activation. Otherwise, VBB should remain
open, or connected to ground as shown in Table 2, jumper JP8. Figure 2 depicts how the S3045 Evaluation
Board can be connected for SONET/SDH measurements, and shows all of the DIP switch settings, and the
LVPECL power supply requirements. This is accomplished by setting the VBB Bias voltage from an external
voltage supply. For SONET testers that need 50 Ohm’s to –2V, set VBB Bias to -5.2V. External test equipment
with standard LVPECL or PECL may interface to the S3045 Evaluation Board, as indicated in Figure 3.
