DESCRIPTION 1.1. Overview The 92HD71B is a family of high fidelity, 4-channel audio codecs compatible with the Intel High Definition (HD) Audio Interface. The 92HD71B codecs provide high quality, HD Audio capability to notebook and cost sensitive desktop PC applications. 92HD71B variants: PartNumber DAC SNR # of Ports Digital Mixer Hi-Perf. Analog Mixer 92HD71B8 92HD71B7 92HD71B5 103 95 95 6 6 4 Yes Yes Yes Yes Yes No The higher performance and quality of IDT's audio solutions brings consumer electronics level performance to notebook and desktop PCs. 92HD71B8 is designed to meet or exceed premium logo requirements for Microsoft's Windows Logo Program (WLP) 3.09 and revision 4 as indicated in WLP 3.09. The 92HD71B8 provides stereo 24- bit, full duplex resolution supporting sample rates up to 192kHz by the DAC and ADC. The 92HD71B8 SPDIF outputs support sample rates of 192kHz, 96kHz, 88.2kHz, 48kHz, and 44.1kHz. Additional sample rates are supported by the driver software. The 92HD71B8 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 92HD71B8 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 92HD71B8 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 92HD71B8 may be configured for +3dBV full scale output levels by using a vendor specific verb.

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 92HD71B8, ensure that there are no conflicts between the output ports on 92HD71B8 and existing circuitry. Table 1.

Jack Detect Plugs inserted to a jack on Ports A, B, C, & D are detected using SENSE_A. Plugs inserted to a jack on Ports E & F are detected using SENSE_B. The following table summarizes the proper resistor tolerances for different analog supply voltages. Table 2.

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.

Mono Output The MONO Output is connected to pin 32 and has an independent mute (see the Widget listing for details). The MONO Output derives its input from the output of the summing node after the mono mux. The following sources are available for the mono pin: DAC0 Output: When enabled (by using port connection list), both DAC0 Outputs are summed together. IDTTM CONFIDENTIAL AND PROPRIETARY 4-CHANNEL HD AUDIO CODEC OPTIMIZED FOR LOW POWER 14 92HD71B8 V 0.91 09/07 92HD71B8 4-CHANNEL HD AUDIO CODEC OPTIMIZED FOR LOW POWER PC AUDIO DAC1 Output: When enabled (by using port connection list), both DAC1 Outputs are summed together. 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 92HD71B8. 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 Inport1_Mux 1.4.8. Input Multiplexers 92HD71B8 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 92HD71B8 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 four possible inputs: * * * * DMIC 0 DMIC1 InPortMux (ADC0 selects inport0_mux / ADC1 selects inport1_mux) Mixer output 1.4.10. Power Management The following table describes what functionality is active in each power state The D3-default state is available for HD Audio compliance. The programmable values, exposed via vendor-specific settings, are under the IDT Device Driver control for further power reduction.

Place part into D3 and power down all ports (using vendor specific verbs) before powering down Ref Top. 6.Obviously not active if BITCLK is not running (Controller in D3). 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 IDTTM CONFIDENTIAL AND PROPRIETARY 4-CHANNEL HD AUDIO CODEC OPTIMIZED FOR LOW POWER 16 92HD71B8 V 0.91 09/07 92HD71B8 4-CHANNEL HD AUDIO CODEC OPTIMIZED FOR LOW POWER PC AUDIO stream id "Strm= N" to both ADC0 and ADC1.

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. 92HD71B8 supports the following digital microphone configurations: Table 8. Valid Digital Mic Configurations Digital Mics 0 Data Sample N/A ADC Conn.

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.

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 92HD71B8 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 24 92HD71B8 V 0.91 09/07 IDTTM CONFIDENTIAL AND PROPRIETARY 4-CHANNEL HD AUDIO CODEC OPTIMIZED FOR LOW POWER 92HD71B8 4-CHANNEL HD AUDIO CODEC OPTIMIZED FOR LOW POWER 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. Figure 8.

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. Table 15.
