• Manufacturer: Realtek Semiconductor Corporation

7.1.2.
The HDA controller supports two SDOs for the outbound stream, up to 15 SDIs for the inbound stream.
RST#, BCLK, SYNC, SDO0, and SDO1 are driven by controller to codecs. Each codec drives its own
point-to-point SDI signal(s) to the controller.
Figure 10 shows the possible connections between the HDA controller and codecs:
• Codec 0 is a basic connection. There is one single SDO and one single SDI for normal transmission
• Codec 1 has two SDOs for doubled outbound rate, a single SDI for normal inbound rate
• Codec 3 supports a single SDO for normal outbound rate, and two SDIs for doubled inbound rate
• Codec N has two SDOs and multiple SDIs
The multiple SDOs and multiple SDIs are used to expand the transmission rate between controller and
codecs. Section 7.2 Frame Composition, page 18, describes the detailed outbound and inbound stream
compositions for single and multiple SDOs/SDIs.
The connections shown in Figure 10 can be implemented concurrently in an HDA system. The ALC262
is designed to receive a single SDO stream.
