SINGLE CHIP PC AUDIO SYSTEM, CODEC+SPEAKER AMPLIFIER+CAPLESS HP+LDO
1. DESCRIPTION
1.1. Overview
The 92HD91 audio CODEC provides stereo 24- bit, full duplex resolution supporting sample rates up
to 192kHz by the DAC and ADC. SPDIF outputs support sample rates of 192kHz, 96kHz, 88.2kHz,
48kHz, and 44.1kHz. Additional sample rates are supported by the driver software.
An integrated BTL stereo amplifier is ideal for driving 4ohm or 8ohm integrated speakers in mobile
and ultra-mobile computers. For desktop computers or mobile computers using only one speaker,
the BTL output stage may be configured to support a single mono speaker.
The 92HD91 audio CODEC supports a wide range of desktop and laptop configurations. The 2 inde-
pendent SPDIF output interfaces provide connectivity to consumer electronic equipment or to a
home entertainment system. Simultaneous HDMI and SPDIF output is possible. All inputs can be
programmed with 0-30 dB gain in 10 dB steps allowing for line or microphone use of any input.
Port presence detect capabilities allow the CODEC to detect when audio devices are connected to
the CODEC. The fully parametric Internal EQ can be initiated upon headphone jack insertion and
removal for protection of notebook speakers.
The 92HD91 audio CODEC operates with a 3.3V digital supply and a 5V (4.75V allowed when using
external voltage regulator) analog supply. It allows for 1.5V and 3.3V HDA signaling; the correct sig-
nalling level is selected dynamically based on the power supply voltage on the DVDD-IO pin.
The 92HD91 audio CODEC is offered in a 48-pin QFN Environmental (ROHS) package.
