description

The TLV320AIC27 comprises a stereo 18-bit codec (that is, 2 ADCs and 4 DACs), plus a comprehensive analog

mixer with four sets of stereo inputs, plus one phone input, two microphone inputs, and one PC-beep input.

Additionally, on-chip reference circuits generate the necessary bias voltages for the device, and a bidirectional

serial interface allows transfer of control data, DAC, and ADC words to and from the AC’97 controller. The

TLV320AIC27 is fully compliant with Revision 2.1 of the AC’97 specification.

The TLV320AIC27 has the ADC and DAC functions implemented using oversampled, or sigma-delta,

convertersanduseson-chipdigitalfilterstoconverttheseone-bitsignalstoandfromthe48ksps, 16/18-bitPCM

words that the AC’97 controller requires. The digital and analog sections of the device are powered separately

to optimize performance, and 3.3-V digital and 5-V analog supplies may be used on the same device to further

optimize performance. Digital IOs are 5-V tolerant when the analog supplies are 5 V. Therefore, the

TLV320AIC27 may be connected to a controller running on 5-V supplies, but use 3.3 V for the digital section

of the TLV320AIC27. The TLV320AIC27 is also capable of operating with a 3.3-V supply only (digital and

analog).

When using the TLV320AIC27 codec, the AC’97 controller may be selected from Texas Instruments family of

DSPs. The combination of the computing power of the TI DSP and the high audio performance of the

TLV320AIC27 constitutes a complete solution for various applications. The ability to power down sections of

the device selectively, and the option to alternate the master clock, and hence sample rates, makes such

applications as telecommunications, audio, teleconferencing, and USB, possible.

Additional features added to the Intel AC’97 specification, such as the EAPD (external amplifier power down)

bit and internal connection of PC beep to the outputs when the device is reset are supported, as well as optional

features such as variable sample rate support.

There are four modes of operation.

Basic (2-channel)

6-channel I S

ESD Sensitive Device. This device is manufactured on a CMOS process. It it therefore generically susceptible to damage from

excessive static voltages. Proper ESD precautions must be taken during handling and storage of this device. As per JEDEC

specifications A112-A and A113-B, this product requires specific storage conditions prior to surface mount assembly. It has been

classified as having a Moisture Sensitivity Level of 2 and as such will be supplied in vacuum-sealed moisture barrier bags.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
