The higher performance and quality of IDT’s audio solutions brings consumer electronics level performance to notebook and desktop PCs. 92HD71B7 is designed to meet or exceed premium logo
requirements for Microsoft’s Windows Logo Program (WLP) 3.09 and revisions 4 as indicated in
WLP 3.09.
The 92HD71B7 provides stereo 24- bit, full duplex resolution supporting sample rates up to 192kHz
by the DAC and ADC. The 92HD71B7 SPDIF outputs support sample rates of 192kHz, 96kHz,
88.2kHz, 48kHz, and 44.1kHz. Additional sample rates are supported by the driver software.
The 92HD71B7 supports a wide range of mobile and desktop 4 channel configurations. The 2 independent SPDIF output interfaces provide connectivity to Consumer Electronic equipment like Dolby
Digital decoders, powered speakers, mini disk drives or to a home entertainment system. Simultaneous WLP compliant HDMI and SPDIF output is possible. All analog input pairs support LINE_IN
and MIC.
MIC inputs can be programmed with 0/10/20/30dB boost. (40dB boost is available using the IDT
driver.) For more advanced configurations, the 92HD71B7 has up to 8 General Purpose I/O (GPIO).
The port presence detect capabilities allow the codecs to detect when audio devices are connected
to the codec. The fully parametric IDT SoftEQ can be initiated or disabled upon headphone jack
removal and insertion for protection of notebook speakers.
The 92HD71B7 operates with a 3.3V digital supply and either 3.3V, 4V, 4.75V or 5V analog supply. It
can also work with 1.5V and 3.3V HDA signaling; the correct signalling level is selected dynamically
based on the power supply voltage on the DVDD-IO pin.
Available in a 48-pin QFP or QFN Environmental (ROHS) packages.

Detailed Description
1.4.1.
Low-voltage High Definition Audio Link Signaling
The 92HD71B is compatible with either 1.5 V or 3.3 V High Definition Audio Link signaling; the voltage selection is performed dynamically based on the input voltage of DVDD_IO. Note that DVDD_IO
is not a logic configuration pin but provides the digital power supply to be used for the High Definition
Audio Link signals.
When in 1.5 V mode, the 92HD71B can correctly decode BITCLK, SYNC, RESET# and SDO
because they operate at 1.5 V. Additionally, it will drive SDI_CODEC at 1.5 V. None of the GPIOs are
affected, as they always function at their nominal voltage (DVDD or AVDD).
1.4.2.
Port Functionality
Single function (Input only / output only) ports allow for the highest possible performance.
•
Port A supports
• Headphone Out
• Line Out
•
Port D supports
• Line Out
•
Ports B and C support
• Line In
• Mic with 0/10/20/30/40 dB Mic boost4
•
Mono Output cannot be reconfigured
•
Port E supports
• Line In
• Mic with 0/10/20/30/40 dB Mic boost4
•
Port F supports
• Line Out
Note4: 40dB boost requires using the IDT driver. When the 40dB mic boost feature is enabled, additional gain increases greater than 6dB may result in significant audio quality degradation of the
microphone audio input. In particular, when the 40dB MIC boost is active, the SNR, THD+N and DC
offset will significantly degrade regardless of the input signal level.
1.4.3.
Port Characteristics
Ports are designed to be dedicated inputs or outputs only. Universal (Bi-directional) jacks are not
supported. Port A is designed to drive a set of 32 ohm (nominal) headphones or a 10K (nominal)
load with on board shunt resistance as low as 20K ohms (typical - used to maintain coupling CAP
bias.) Line Level outputs are intended to drive an external 10K speaker load (nominal) and an on
board shunt resistor of 20-47K (nominal). However, applications may support load impedances of 5K
ohms and above. Input ports are 47K impedance (nominal) at the pin.
DAC full scale outputs and intended full scale input levels are 1V rms. Line output ports and Head-on
output ports on the 92HD71B7 may be configured for +3dBV full scale output levels by using a vendor specific verb.

Output ports are always on to prevent pops/clicks associated with charging and discharging output
coupling capacitors. This maintains proper bias on output coupling caps even in D3 as long as AVDD
is available. Unused ports should be left unconnected. When updating existing designs to use
92HD71B7, ensure that there are no conflicts between the output ports on 92HD71B7 and existing
circuitry.

SPDIF Output
All SPDIF Outputs can operate at 44.1kHz, 48kHz, 88.2kHz, 96kHz and 192KHz as defined in the
Intel High Definition Audio Specification with resolutions up to 24 bits. This insures compatibility with
all consumer audio gear and allows for convenient integration into home theater systems and media
center PCs.
A second independant SPDIF Output is provided as an option for WLP compliant HDMI and SPDIF
outputs. Its function is identical to the primary SPDIF output.

Input Mixer: When enabled (by using mono mix connection list and DAC mixer), both mixer outputs
are summed together.
The stereo inputs are scaled by -6dB and then summed to provide an output that is the average of
the two inputs. The full scale output at mono out is designed to be about 0dBV. It is not possible to
adjust to a +3dBV output level.
1.4.7.
Analog Mixer
An analog mixer is available on the 92HD71B7. The mixer supports independent gain (-34.5 to
+12dB in 1.5dB steps) on each input as well as independent mutes on each input.
The following inputs are available:

•
DAC0
•
DAC1
•
Analog PC_Beep
•
Inport0_Mux

Input Multiplexers
92HD71B7 implements 2 port input multiplexers. These multiplexers incorporate the microphone
boost function (0, 10dB, 20dB, 30dB, and 40dB gain) as an output amp and allow a preselection of
one of three possible inputs:
Port B
Port C
Port E
NOTE: Changing the Input multiplexer setting will affect both the analog mixer and the ADC.
1.4.9.
ADC Multiplexers
92HD71B7 implements 2 ADC input multiplexers. These multiplexers incorporate the ADC record
gain function (0 to +22.5dB gain in 1.5dB steps) as an output amp and allow a preselection of one of

1.4.11.
Multi-channel capture
The capability to assign multiple “ADC Converters” to the same stream is supported to meet the
microphone array requirements of Vista and future operating systems. Single converter streams are
still supported and is done by assigning unique non zero Stream IDs to each converter. All capture
devices (ADCs 0 and 1) must be used to create a multi-channel input stream. There are no restrictions regarding digital microphones.
The ADC Converters can be associated with a single stream as long the sample rate and the bits per
sample are the same. The assignment of converter to channel is done using the “CnvtrID” widget
and is restricted to even values. The ADC converters will always put out a stereo sample and therefore require 2 channels per converter.
The stream will not be generated unless all entries for the targeted converters are set identically, and
the total number of assigned converter channels matches the value in the NmbrChan field. These
are listed the “Multi-Converter Stream Critical Entries.” table.
An example of a 4 Channel Steam with ADC0 supplying channels 0&1 and ADC1 supplying channels 2 & 3 is shown below. A 4 Channel stream can be created by assigning the same non-zero

EAPD
The EAPD pin (pin 47) also supports SPDIF and GPIO functions. The pin defaults to EAPD after
power on reset and will remain in EAPD mode until either GPIO is enabled for pin 47 or the port I/O
is enabled to support SPDIF. The EAPD value is reflected on the EAPD pin; a 1 causes the external
amplifier to power up, and a 0 causes it to power down. When the EAPD value = 1, the EAPD pin
must be placed in a state appropriate to the current power state of the associated Pin Widget even
though the EAPD value may remain 1. The default state of this pin is 0 (driving low) and a Pull-down
prevents the line from floating high when the part is in reset.

Digital Microphone Support
The digital microphone interface permits connection of a digital microphone(s) to the CODEC via the
DMIC0, DMIC1, and DMIC_CLK 3-pin interface. The DMIC0 and DMIC1 signals are inputs that carry
individual channels of digital Mic data to the ADC. In the event that a single microphone is used, the
data is ported to both ADC channels.
The DMIC_CLK output is controllable from 4.704Mhz, 3.528Mhz, 2.352Mhz, 1.176Mhz and is synchronous to the 24Mhz internal clock. The default frequency is 2.352Mhz.
92HD71B7 supports the following digital microphone configurations:

Volume/Digital Microphone/GPIO Selection
To determine which function is actually enabled on pins2 and 4, the order of precedence is followed:
1) If the GPIOs are enabled, they override both Volume Control and Digital Mics
2) If the GPIOs are not enabled through the AFG, then at reset, the Volume control is enabled with
the weak pull-up.

3) If BIOS or other software application enables either Digital Microphones inputs through the Configuration Default Register, the Volume is disconnected and the pull-ups are disconnected with the
weak pull-downs enabled.
1.4.16.3.
VRefOut/GPIO Selection
Two functions are available on pin 31. To determine which function is actually enabled, the order of
precedence is followed:
1) If the GPIO4 function is enabled, it overrides VRefOut-E
2) If the GPIO4 function is not enabled through the AFG, then, at reset the VrefOut-E is enabled.
3) If using pin 31 as GPIO, make sure to incorporate a 10K ohm external pull-up to AVDD to prevent
the pin from floating in GPI mode and to allow proper operation in open-drain GPO mode.
1.4.17.
External Volume Control
92HD71B7 incorporates a 2-pin volume control interface. Volume up, down, and mute functions are
easily implemented using 2 push-button switches. The CODEC provides internal pull-up resistors
simplifying external CODEC circuitry. Also, repeat and direct modes of operation add flexibility to the
interface. The typical usage model is for front panel master volume buttons on an entertainment PC,
or case mounted hardware volume control for mobile platforms.
1.4.17.1.
Theory of Operation
The codec monitors the volume up/down inputs for a change of state from high to low, and waits for
the inputs to settle. If the inputs have not settled by the end of the de-bounce period, then the value
at the end of the period is used. A 0 (low voltage) on the Down pin will decrement the volume register, while a 0 on the Up pin will increment the volume register. If both inputs are 0 at the same time,
then the volume register will be set to its lowest value (mute). Pressing Up, Down, or both buttons at
the same time when the volume control interface is in mute mode, will cause the part to un-mute.
The de-bounce / repeat rate is selectable from 2.5Hz to 20Hz in 2.5Hz increments using the Volume
Knob VCSR0 verb (FE0) Rate bits (bits 2:0). This value is used for both de-bounce and repeat rates.
The de-bounce period is the time that the CODEC waits for the inputs to settle, and the repeat rate is
the rate at which the CODEC will increment/decrement the volume if a volume button is pushed and
held. When a falling edge is detected on either one of the volume control pins, the codec will wait for
(1/Rate) seconds for the input to settle. If the Continuous bit is set in the Volume Knob VCSR0 verb
(bit 3), then the codec will wait for the de-bounce period to expire then repeatedly increment or decrement the volume register at the rate specified in the Rate bits until the button is released.
1.4.17.2.

Modes of Operation
DIRECT MODE
• In Direct mode, the Volume Knob widget directly controls the volume of all of the DACs in
the part. The volume in the Volume Knob widget acts as the master volume and limits the
maximum volume for each of the DAC amplifiers. The amp gain for each of the DACs can
also be adjusted using the DAC amplifiers. However, the actual gain for an individual DAC
will be the sum of the Volume Knob volume and the DAC amplifier volume. For example, if
the DAC amplifier gain is set to 0x7F (0dB) and the Volume Knob volume is set to 0x3F
(-48dB) the resulting gain would be -48dB. If the combination of gains is less than -95.25dB

PC AUDIO
(the equivalent to a value of 0x0 for the DAC or Volume Knob volume settings) then the
actual gain will be -95.25dB. For example, if the Volume Knob is set to 0x3F (-48dB) and the
DAC amplifier volume is set to 0x1F (-72dB) then the DAC volume will be set to -95.25dB.
Direct mode is enabled by setting bit 7 in the Volume Knob Cntrl verb (F0F). The volume is
reflected in the Volume Knob Cntrl bits 6:0 and the step size is 0.75dB. In direct mode, software can read or write the volume in the Volume Knob widget.
INDIRECT MODE
• In indirect mode, the Volume Knob widget does not directly control the DAC amplifier gains.
An event on the volume Up/Down pins will increment/decrement the value in the Volume
Knob Cntrl verb (F0F) volume bits (bits 6:0) just as in Direct mode. However, instead of
adjusting the DAC amplifier gain, an unsolicited response is generated (if enabled) and the
control software must read the volume in the Volume Knob widget and take appropriate
action. Indirect mode is particularly useful when it is undesirable to control all of the DAC
amplifier volumes at the same time, or when implementing ADC volume control.
• In indirect mode, there are only 128 volume levels in the Volume Knob Cntrl volume bits, the
value will not go beyond the lower and upper limits (0x0 or 0x7F), and an unsolicited
response will not be generated if an input event tries to go beyond these limits. Therefore, it
is the responsibility of the controlling software to monitor the volume in the Volume Knob
Widget and take appropriate action.
• Indirect mode is enabled by clearing bit 7 in the Volume Knob Cntrl verb (F0F). The volume
is reflected in the Volume Knob Cntrl bits 6:0 and the step size is 0.75dB. In direct mode,
software can read or write the volume in the Volume Knob widget.
1.4.17.3.
Hardware Implementation
The Volume Knob interface is comprised of two input pins, CODEC pins 2 and 4. Both pins have
internal pull-up resistors, so only two push button switches are required for most implementations.
Typically, a series resistor and shunt capacitor are used to help reduce noise and prevent damage
from ESD and other potential faults. An example circuit is shown below.

1.Dynamic Range is the ratio of the full scale signal to the noise output with a -60dBFS signal as defined in AES17 as SNR in the
presence of signal and outlined in AES6id, measured “A weighted” over 20 Hz to 20 kHz bandwidth.
2.Ratio of Full Scale signal to idle channel noise output is measured “A weighted” over a 20 Hz to a 20 kHz bandwidth.
(AES17-1991 Idle Channel Noise or EIAJ CP-307 Signal-to-noise Ratio).
3.THD+N ratio as defined in AES17 and outlined in AES6id,non-weighted, over 20 Hz to 20 kHz bandwidth.Results at the jack
are dependent on external components and will likely be 1 - 2dB worse.
4.Peak-to-Peak Ripple over Passband meets ± 0.125dB limits, 48 kHz or 44.1 kHz Sample Frequency. 1dB limit.
5.Stop Band rejection determines filter requirements. Out-of-Band rejection determines audible noise.
6.The integrated Out-of-Band noise generated by the DAC process, during normal PCM audio playback, over a bandwidth 28.8
to 100 kHz, with respect to a 1 Vrms DAC output.
7.Gain drift is the change in analog volume control gain for each step across the supported 0 oC TO 70 oC temperature range
referenced to the 25 oC gain value and specified in ppm per oC
8.± 1dB limits for Line Output & 0 dB gain, at -20dBV
9.Spurious tone rejection is tested with ADC dither enabled and compared to ADC performance without dither.
10.Does not include 32Ω load headphone power.
11.Can be set to 0.5 or 0.8 AVdd.

6. PIN CONFIGURATION DEFAULT REGISTER SETTINGS
The configuration default registers are 32-bit registers required for each pin widget. These registers are normally used
by the CODEC driver to determine the configuration of jacks and devices attached to the CODEC. When the CODEC is
powered on, these registers are loaded with the default values provided by IDT for typical system usage, and are
loaded in a way that is compatible with the Microsoft Universal Audio Architecture (UAA) driver. The values can be
overridden by IDT customers according to their system configuration. Table 15 shows the Pin Widget Configuration
Default settings.

There are two types of responses: Solicited and Unsolicited. Solicited responses are provided as a
direct response to an issued command and will be provided in the frame immediately following the
command. Unsolicited responses are provided by the CODEC independent of any command. Unsolicited responses are the result of CODEC events such as a jack insertion detection. The formats for
Solicited Responses and Unsolicited Responses are shown in Tables 18 and 19 respectively. The
“Tag” field in bits [31:28] of the Unsolicited Response identify the event.

Divider
RW
00
Enable internal PC-Beep generation.
Divider == 00h disables internal PC
Beep generation and enables normal
operation of the codec. Divider != 00h
generates the beep tone on all Pin Complexes that are currently configured as
outputs. The HD Audio spec states that
the beep tone frequency = (48kHz HD
Audio SYNC rate) / (4*Divider), producing tones from 47 Hz to 12 kHz (logarithmic scale). This part can selectively
generate tones with frequency = 48KHz
* (257 - Divider) / 1024, yielding a linear
range from 12kHz to 93.75Hz in steps of
46.875Hz. If the FreqShift bit is set, then
the beep tones generated have frequency = 48KHz * (513 - Divider) / 1024,
yielding a range of 24kHz to
12093.75Hz in steps of 46.875Hz.
