description

The TLV320AD11A is a high-speed codec for remote terminal-side (RT) modems that support the ANSI T1.413

[Issue 2 discrete multi-tone (DMT) asymmetric digital subscriber line (ADSL) access] and ITU G.992.1

standards. It is a low-power device that includes five major functional blocks: transmitter, receiver, clock,

reference, and host interface. It is designed to work with the Texas Instruments TLV320AD12 central office-side

(CO) codec.

The device’s transmit channel consists of the following functional blocks: 138 kHz digital low-pass filter,

bypassable 25.875 kHz digital high-pass filter, 14-bit high speed DAC, 138 kHz analog low-pass filter, transmit

attenuator, and an echo cancellation channel. The receiver channel consists of two programmable-gain

amplifiers, a frequency equalizer, a 1.104-MHz low-pass analog filter, a 14-bit high speed ADC, and a

1.104-MHz low-pass digital filter. The clock circuit divides a 35.328-MHz frequency from an external VCXO

down to the necessary frequencies used throughout the device. The frequency of the external VCXO is

controlled by a 12-bit onboard voltage output DAC. An onboard reference circuit generates a 1.5-V reference for

the converters.

The device has a parallel port for data transfer and a serial port for control. The parallel port is 16 bits wide and is

reserved for moving data between the codec and a DSP such as the Texas Instruments TMS320C6XX.

Configurationis done via a serial port. The device can be powered down via a dedicated pin, or through software

control, to reduce heat dissipation. Additionally, there is a general-purpose (GP) port consisting of eight output

terminals for control of external circuitry.

The TLV320AD11A codec is available in a 100-pin PZ PQFP package and is characterized for operation in the

temperature range of –40°C to 85°C.

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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
