5.2.3.2 bi-direction Point-point

(1)PCI: Freescale MPC8247的PCI interface与Broadcom BCM5645 PCI互联，2in走线，33MHz。HyperLynx.

A1不端接 MPC8247 to BCM5645

A2不端接 BCM5645 to MPC8247

B1 双向端接MPC8247 to BCM5645(39ohm)

B2 双向端接 BCM5645 to MPC8247(39ohm)

端接之后，信号质量有明显的改善。

(2)localbus: PLX9054 localbus 和AudioCodes AC491(DSP) localbus互联。5in，35MHz。

A1 不端接 PLX9054 to AC491

A2 不端接 AC491 to PLX9054

B1 端接 PLX9054 to AC491 (33ohm)

B2 端接 AC491 to PLX9054 (33ohm)
