High Definition Audio Link Protocol 7.1. Link Signals The High Definition Audio (HDA) link is the digital serial interface that connects the HDA codecs to the HDA Controller. The HDA link protocol is controller synchronous, based on a 24.0MHz BIT-CLK sent by the HDA controller. The input and output streams, including command and PCM data, are isochronous with a 48kHz frame rate. Figure 4 shows the basic concept of the HDA link protocol. Previous Frame BCLK Frame SYNC= 8 BCLK SYNC Tframe_sync = 20.833 s (48KHz) Next Frame Stream 'A' Tag (Here 'A' = 5) Stream 'B' Tag (Here 'B' = 6) SDO Command Stream (40-bit data) Stream 'A' Data Stream 'B' Data SDI Response Stream (36-bit data) Stream 'C' Tag Stream 'C' Data (n bytes + 10-bit data) RST# Figure 4.

Link Signal Definitions Description 24.0MHz bit clock sourced from the HDA controller and connecting to all codecs. 48kHz of signal is used to synchronize input and output streams on the link. It is sourced from the HDA controller and connects to all codecs. Serial data output signal driven by the HDA controller to all codecs. Commands and data streams are carried on SDO. The data rate is double pumped; the controller drives data onto the SDO, the codec samples data present on SDO with respect to each edge of BCLK. The HDA controller must support at least one SDO. To extend outbound bandwidth, multiple SDOs may be supported. Serial data input signal driven by the codec. This is point-to-point serial data from the codec to the HDA controller. The controller must support at least one SDI, and up to a maximum of 15 SDI's can be supported. SDI is driven by the codec at each rising edge of BCLK, and sampled by the controller at each rising edge of BCLK. SDI can be driven by the controller to initialize the codec's ID. Active low reset signal. Asserted to reset the codec to default power on state. RST# is sourced from the HDA controller and connects to all codecs. SDI RST# Table 6.

Signaling Topology 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 6 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 13 describes the detailed outbound and inbound stream compositions for single and multiple SDOs/SDIs. The connections shown in Figure 6 can be implemented concurrently in an HDA system. The ALC888T-GR is designed to receive a single SDO stream. SDI14 . . .

Outbound Frame - Single SDO An outbound frame is composed of one 32-bit command stream and multiple data streams. There are one or multiple sample blocks in a data stream. Only one sample block exists in a stream if the HDA controller delivers a 48kHz rate of samples to the codec. Multiple sample blocks in a stream means the sample rate is a multiple of 48kHz. This means there should be two blocks in the same stream to carry 96kHz samples (Figure 7). For outbound frames, the stream tag is not in SDO, but in the SYNC signal. A new data stream is started at the end of the stream tag. The stream tag includes a 4-bit preamble and 4-bit stream ID (Figure 8). To keep the cadence of converters bound to the same stream, samples for these converters must be placed in the same block. Previous Frame A 48kHz Frame is composed of Command stream and multiple Data streams Stream 'A' Tag (Here 'A' = 5) Stream 'X' Tag (Here 'X' = 6) Next Frame Frame SYNC SYNC SDO Command Stream Stream 'A' Data Stream 'X' Data 0s Sample Block(s) Block 1 Block 2 Sample 2 ... lsb .. . .. .

Outbound Frame - Multiple SDOs The HDA controller allows two SDO signals to be used to strip outbound data, completing transmission in less time to get more bandwidth. If software determines the target codec supports multiple SDO capability, it enables the `Strip Control' bit in the controller's Output Stream Control Register to initiate a specific stream (Stream `A' in Figure 9) to be transmitted on multiple SDOs. In this case, the MSB of the data stream is always carried on SDO0, the second bit on SDO1 and so forth. SDO1 is for transmitting a striped stream. The codec does not support multiple SDOs connected to SDO0. To guarantee all codecs can determine their corresponding stream, the command stream is not striped. It is always transmitted on SDO0, and copied on SDO1. Figure 9. Striped Stream on Multiple SDOs 7.1+2 Channel High Definition Audio Codec for VoIP Applications 14 Track ID: JATR-1076-21 Rev. 1.1 www..com ALC888T-GR Datasheet 7.2.3. Inbound Frame - Single SDI An Inbound Frame - A single SDI is composed of one 36-bit response stream and multiple data streams. Except for the initialization sequence (turnaround and address frame), the SDI is driven by the codec at each rising edge of BCLK. The controller also samples data at the rising edge of BCLK (Figure 10). The SDI stream tag is not carried by SYNC, but included in the SDI. A complete SDI data stream includes one 4-bit stream tag, one 6-bit data length, and n-bit sample blocks. Zeros will be padded if the total length of the contiguous sample blocks within a given stream is not of integral byte length (Figure 11).

Inbound Frame - Multiple SDIs A codec can deliver data to the controller on multiple SDIs to achieve higher bandwidth. If an inbound stream exceeds the data transfer limits of a single SDI, the codec can divide the data into separate SDI signals, each of which operate independently, with different stream numbers at the same frame time. This is similar to having multiple codecs connected to the controller. The controller samples the divided stream into separate memory with multiple DMA descriptors, then software re-combines the divided data into a meaningful stream. SYNC Frame SYNC SDI 0 Response Stream Tag A Stream 'A' Data A Stream 'B' SDI 1 Response Stream Tag B Data B 0s 0s Stream 'X' Stream 'Y' Codec drives SDI0 and SDI1 Stream A, B, X, and Y are independent and have separate IDs Figure 12. Codec Transmits Data Over Multiple SDIs 7.2.5. Variable Sample Rates The HDA link is designed for sample rates of 48kHz. Variable rates of sample are delivered in multiple or sub-multiple rates of 48kHz. Two sample blocks per frame result in a 96kHz delivery rate, one sample block over two frames results in a 24kHz delivery rate. The HDA specification states that the sample rate of the outbound stream be synchronized by the controller, not by the codec. Each stream has its own sample rate, independent of any other stream. The HDA controller supports 48kHz and 44.1kHz base rates. Table 7, page 17, shows the recommended sample rates based on multiples or sub-multiples of one of the two base rates. Rates in sub-multiples (1/n) of 48kHz are interleaving n frames containing no sample blocks. Rates in multiples (n) of 48kHz contain n sample blocks in a frame. Table 8, page 17, shows the delivery cadence of variable rates based on 48kHz. The HDA link is defined to operate at a fixed 48kHz frame rate. To deliver samples in (sub) multiple rates of 44.1kHz, an appropriate ratio between 44.1kHz and 48kHz must be maintained to avoid frequency drift. The appropriate ratio between 44.1kHz and 48kHz is 147/160. Meaning 147 sample blocks are transmitted every 160 frames. The cadence "12-11-11-12-11-11-12-11-11-12-11-11-11- (repeat)" interleaves 13 frames containing no sample blocks in every 160 frames. It provides a low long-term frequency drift for 44.1kHz of delivery rate. Rates in sub-multiples (1/n) of 44.1kHz also follow this cadence AND interleave n empty frames. Rates in multiples (n) of 44.1kHz applying this cadence contain n sample blocks in the non-empty frame AND interleave an empty frame between non-empty frames (Table 9, page 18). 7.1+2 Channel High Definition Audio Codec for VoIP Applications 16 Track ID: JATR-1076-21 Rev. 1.1 www..com ALC888T-GR Datasheet Table 7.

Reset and Initialization There are two types of reset within an HDA link: * * Link Reset. Generated by assertion of the RST# signal, all codecs return to their power on state Codec Reset. Generated by software directing a command to reset a specific codec back to its default state An initialization sequence is requested after any of the following three events: 1. 2. 3. Link Reset Codec Reset Codec changes its power state (for example, hot docking a codec to an HDA system) 7.3.1. 1. 2. 3. Link Reset A link reset may be caused by 3 events: The HDA controller asserts RST# for any reason (power up, or PCI reset) Software initiates a link reset via the `CRST' bit in the Global Control Register (GCR) of the HDA controller Software initiates power management sequences. Figure 13, page 20, shows the `Link Reset' timing including the `Enter' sequence ( ~ ) and `Exit' sequence ( ~ ) Enter `Link Reset': Software writes a 0 to the `CRST' bit in the Global Control Register of the HDA controller to initiate a link reset When the controller completes the current frame, it does not signal the normal 8-bit frame SYNC at the end of the frame The controller drives SYNC and all SDOs to low. Codecs also drive SDIs to low The controller asserts the RST# signal to low, and enters the `Link Reset' state All link signals driven by controller and codecs should be tri-state by internal pull low resistors 7.1+2 Channel High Definition Audio Codec for VoIP Applications 19 Track ID: JATR-1076-21 Rev. 1.1 www..com ALC888T-GR Datasheet Exit from `Link Reset': If BCLK is re-started for any reason (codec wake-up event, power management, etc.) Software is responsible for de-asserting RST# after a minimum of 100s BCLK running time (the 100sec provides time for the codec PLL to stabilize) Minimum of 4 BCLK after RST# is de-asserted, the controller starts to signal normal frame SYNC When the codec drives its SDI to request an initialization sequence (when the SDI is driven high at the last bit of frame SYNC, it means the codec requests an initialization sequence) Previous Frame 4 BCLK 4 BCLK Link in Reset >=100 usec >= 4 BCLK Initialization Sequence BCLK SYNC 2 Normal Frame SYNC is absent Driven Low Normal Frame SYNC 8 Driven Low Pulled Low Wake Event 9 Pulled Low SDOs SDIs RST# 1 3 Driven Low Pulled Low Pulled Low 4 5 6 7 Figure 13.

The codec will send Solicited Response data in the next frame, without regard to the Set (Write) or Get (Read) command. The 32-bit Response is interpreted by software, opaque to the controller. Unsolicited Responses are sent by the codec independently of software requests. Jack Detection or GPI status information can be actively delivered to the controller and interpreted by software.

Power Management The ALC888T-GR does not support Wake-Up events when in low power mode. All power management state changes in widgets are driven by software. Table 14 shows the System Power State Definitions. In the ALC888T-GR, all the widgets, including output/input converters, support power control. Software may have various power states depending on system configuration. Table 15 indicates those nodes that support power management. To simplify power control, software can configure whole codec power states through the audio function (NID=01h). Output converters (DACs) and input converters (ADCs) have no individual power control to supply fine-grained power control. Power States D0 D1 D2 D3 (Hot) D3 (Cold) Table 14.
