PCI-6CH C3DX series /PCI-Based HRTF 3D Extension Positional Audio Chip

10. CMI8738 PCI Audio Adapter Layout Notes

1. The wires of analog circuits(chip pin64-80) must be wider than 12mil.

2. Placing digital signals such as SPDIF IN/OUT(pin86, 98) and TXD/RXD(pin88,89) near the

analog signals should be avoided. However, if these signals have to be adjacent, please

place ground between these digital and analog signal wires to isolate noises.

3. The whole PCB grounding should be well-organized(The ground must be placed as much

as possible. Also, the ground of both the component and the solder sides should be drilled

as much as possible.).

4. The grounding under CMI8738 should be well-organized as mentioned above.

5. The regulator(78L05) must be placed near the chip as much as possible.

6. The chip and the circuits need independent power supply regulators to prevent

insufficient currents.
