Hardware Reference

3.0Hardware Reference

For a hardware layout of the BX400ii Interposer Board, refer to Figure 5 on page 13. For board dimensions and keepout space requirements, refer to Figure 2 and Figure 3 on page 8.

3.1Connector Definitions

Changes to the hardware are not required for the BX400ii Interposer Board. If necessary, you can refer to the Mobile Pentium® II Processor at 233 MHz, 266 MHz and 300 MHz datasheet (order number 243669), Intel® Pentium® II Processor Mobile Module: Mobile Module Connector 2 (MMC-2)datasheet (order number 243668) for connector definitions.

3.2Jumper Settings

Changes to the jumper settings are not required for normal operation of the BX400ii Interposer Board.

3.2.1Voltage Regulator Settings

The voltage setting for the VCC core is determined by the VID pins, which are signal outputs of the Mobile Pentium II processor. Jumper settings are available to vary the VCC core voltage, however, these should only be used for validation/debug purposes. For reference purposes, the jumper settings for the voltage regulator are provided in Table 3.
