ALC269
Datasheet
1. General Description
The ALC269 is a High Definition Audio Codec that integrates a 2+2-channel DAC, a 4-channel ADC,
and a Class-D Speaker Amplifier.
The 2+2-channel DAC supports two independent stereo sound outputs simultaneously. The 4-channel
ADC integrates two stereo and independent analog sound inputs (multiple streaming).
The ALC269 incorporates Realtek converter technology to achieve a 98dB dynamic range playback
quality and a 98dB dynamic range recording quality. It meets the current WLP3.10 (Windows Logo
Program) and future WLP requirements.
The ALC269 also supports stereo digital microphone channels (microphone array) with Acoustic Echo
Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technology simultaneously,
significantly improving voice quality for PC VoIP applications.
As well as basic audio functions, the ALC269 has two independent S/PDIF outputs; one could be used to
connect a PC to high-quality consumer electronic products such as digital decoders and speakers, the
other could provide a dedicated digital output to a HDMI transmitter (common in high end PCs).
There are three integrated power amplifiers. The first is a linear headphone amplifier at port C. The
second headphone amplifier at port A removes the need for external DC blocking capacitors, eliminating
pop noise caused by these capacitors. The third is an integrated stereo Class-D amplifier to directly drive
a mini-speaker. The Class-D amplifier is designed to drive speakers with as low as 4Ω impedance. Its
maximum output power is 2.3W per channel at 5V power supply. The advantage of an integrated Class-D
amplifier in the ALC269 is high efficiency with low power consumption.
The ALC269 integrates five hardware equalizer bands composed of one low-pass filter, one high-pass
filter, and three band-pass filters to compensate for mini-speaker frequency response. All the equalizer
filters are programmable via the BIOS, allowing the equalizer to function without the need to customize
the audio driver.
The ALC269 conforms to Intel’s Audio Codec low power state white paper and is ECR compliant.
Note: ALC269 version differences are listed in section 12 Ordering Information, page 71.

7. 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.

48kHz signal 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. It 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.

7.1.2. 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 ALC269 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 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.

7.2.2.Outbound Frame – Multiple SDO
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 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 9) 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 guarantee 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 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).

7.2.4. Inbound Frame – Multiple SDI
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 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).

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. Link Reset
2. Codec Reset
3. Codec changes its power state (For example, hot docking a codec to an HDA system)
7.3.1. Link Reset
A link reset may be caused by 3 events:
1. The HDA controller asserts RST# 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 13, page 20, 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 RST# 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

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 RST# after a minimum of 100µsec BCLK running time (the
100µsec provides time for the codec PLL to stabilize)
u Minimum of 4 BCLK after RST# is de-asserted, the controller starts to signal normal frame SYNC
v 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)

Verb and Response Format
7.4.1. Command Verb Format
There are two types of verbs: one with 4-Bit identifiers (4-Bit verbs) and 16-Bits of data, the other with
12-Bit identifiers (12-Bit verbs) and 8-Bits of data. Table 10 shows the 4-Bit verb structure of a command
stream sent from the controller to operate the codec. Table 11 is the 12-Bit verb structure that gets and
controls parameters in the codec.

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
All power management state changes in widgets are driven by software. Table 14 shows the System
Power State Definitions.
In the ALC269, all the widgets include 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.

Note1: DVDD-IO must be lower than DVDD.
Note2: PVDD must be greater than AVDD, and keep PVDD-AVDD ≤ 0.8V for best performance.
When (PVDD ≥ AVDD + 1V), THD+N will be degraded when playing at full power output.
Note3: When the Class-D amplifier is operating, surges of PVDD > 7V duration for 0.1ms may damage the amplifier. To
suppress such surges, 10µF tantalum capacitors are required at PVDD1 and PVDD2.
