HMP9701

AC’97 Audio Codec

November 1998

Features

Description

• Fully Compatible with the Audio Codec ‘97 Standard

The HMP9701 is the next generation PC based audio codec

solution. The HMP9701 is fully compatible to the new AC’97

standard and, as such, interfaces to any AC’97 compliant digital

controller. The HMP9701 offers the designer a solution to sat-

isfy the demand for ﬂexibility and improved High Fidelity sound

in a PC environment. As part of the AC’97 PC audio standard

architecture, the HMP9701 helps pave the way for PC’97 com-

pliant desktop, portable and entertainment PCs with a cost

effective high-quality audio solution.

• High Fidelity 16-Bit Σ∆ Converters

- DAC SNR > 80dB

- ADC SNR > 80dB

• Additional A/D for Microphone Pass-Through

• AC Link Serial Interface Compatible with AC’97 Digital

Controllers

• Fixed 48kHz Sampling Rate

• 6 Channel Input Mixer

As the analog front end of the AC’97 chipset, the HMP9701

accepts line level audio inputs from seven different sources and

converts the analog audio to 16-bit digital streams of either ste-

reo or mono data. The 48 Kss data is transmitted to the control-

ler via the AC’97 standard ﬁve wire interface. The controller

sends digital audio data to the HMP9701 to be converted to

analog stereo or monaural line output using two DACs.

• Programmable Powerdown Modes

• 48 Lead TQFP Package

• Single +5V Supply

We include an additional ADC to be used for Acoustic Echo

Canceling needed for video conferencing applications. This

ADC has a dedicated microphone input. It has the same high

quality performance as the stereo ADCs. The small 48 lead

TQFP (Thin 1.5mm and 7mm x 7mm footprint Quad Flat Pack-

age) makes it easy to locate the analog codec close to the ana-

log sources. Thus, reducing noise and lowering the cost of

implementation.

Applications

• Multimedia PC Applications

- Desk Top PCs

- Notebook PCs

- Sound Cards

- Motherboards

• Video Conferencing

• Speaker Phones
