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 3 shows the basic concept of the HDA link protocol.

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. 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.

7.1.2. Signaling Topology

The HDA controller supports two SDOs for the outbound stream, up to 15 SDIs for the inbound stream. RESET#, BCLK, SYNC, SDO0, and SDO1 are driven by the controller to codecs. Each codec drives its own point-to-point SDI signal(s) to the controller.
Figure 5 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, and 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 the controller and codecs. Section 7.2 Frame Composition, page 12, describes the detailed outbound and inbound stream compositions for single and multiple SDOs/SDIs.
The connections shown in Figure 5 can be implemented concurrently in an HDA system. The ALC662 is designed to receive a single SDO stream.

Frame Composition

7.2.1. 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 2 blocks in the same stream to carry 96kHz samples (Figure 6).
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 7).
To keep the cadence of converters bound to the same stream, samples for these converters must be placed in the same block.

7.2.2. Outbound Frame – Multiple SDOs

The HDA controller allows two SDO signals to be used to stripe outbound data, completing transmission in less time to get more bandwidth. If software determines that the target codec supports multiple SDO capability, it enables the ‘Stripe Control’ bit in the controller’s Output Stream Control Register to initiate a specific stream (Stream ‘A’ in Figure 8) to be transmitted on multiple SDOs. In this case, the MSB of stream data 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 ensure that all codecs can determine their corresponding stream, the command stream is not striped. It is always transmitted on SDO0, and copied on SDO1.

7.2.3. Inbound Frame – Single SDI

An Inbound Frame – Single SDI is composed of one 36-bit response stream and multiple data streams. Except for the initialization sequence (turnaround and address frame), SDI is driven by the codec at each rising edge of BCLK. The controller also samples data at the rising edge of BCLK (Figure 9).
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 10).

7.2.4. 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 onto 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.

7.2.5. Variable Sample Rates

The HDA link is designed for sample rates of 48kHz. Variable sample rates 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 8, page 16, 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 9, page 16, 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.
5.1 Channel High Definition Audio Codec 15 Track ID: JATR-1076-21 Rev. 1.3
Page 24
ALC662 Series
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 (see Table 10, page 17).

Reset and Initialization

There are two types of reset within an HDA link:
Link Reset.
Generated by assertion of the RESET# 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:

Link Reset

Codec Reset
Codec changes its power state, e.g., hot docking a codec to an HDA system
7.3.1. Link Reset
Datasheet
A link reset may be caused by any of the following three events:
1. The HDA controller asserts RESET# for any reason (power up, or PCI reset)
2. Software initiates a link reset via the ‘CRST’ bit in the Global Control Register (GCR) of the HDA
controller
3. Software initiates power management sequences. Figure 12, page 19, shows the ‘Link Reset’ timing
including the ‘Enter’ sequence (n~r) and ‘Exit’ sequence (s~v)
Enter ‘Link Reset’:
n Software writes a 0 to the ‘CRST’ bit in the Global Control Register of the HDA controller to initiate a link reset
o As the controller completes the current frame, it does not signal the normal 8-bit frame SYNC at the end of the frame
p The controller drives SYNC and all SDOs to low. Codecs also drive SDIs to low
q The controller asserts the RESET# signal to low, and enters the ‘Link Reset’ state
r All link signals driven by controller and codecs should be tri-state by internal pull-low resistors

ALC662 Series
Exit from ‘Link Reset’:
s If BCLK is re-started for any reason (codec, wake-up event, power management, etc.)
t Software is responsible for de-asserting RESET# after a minimum of 100µs BCLK running time (the
100µsec provides time for the codec PLL to stabilize)
u Minimum of 4 BCLKs after RESET# is de-asserted, the controller starts to signal normal frame SYNC
v The codec drives its SDI to request an initialization sequence (when the SDI is driven high at the last
bit of frame SYNC)

7.4.2. Response Format

There are two types of response from the codec to the controller. Solicited Responses are returned by the codec in response to a current command verb. 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. The ‘Tag’ in Bit[31:28] is used to identify unsolicited events. This tag is undefined in the HDA specifications.

Power Management

The ALC662 does not support Wake-Up events when in low-power mode. All power management state changes in widgets are driven by software. Table 17 shows the System Power State Definitions. Table 18 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.
