Description

The TLV320AD13A is a high-speed coder/decoder (codec) for remote terminal (RT)-side modems that supports ADSL over integrated services digital network (ISDN) solution. The TLV320AD13A is a low-power device composed of five major functional groups for transmit (TX), receive (RX), clock, reference, and host interface. It is designed to work with the Texas Instruments (TI™) TNETD2022D central office (CO)-side codec for ISDN.

The TX channel consists of a 138-kHz to 276-kHz digital bandpass filter, a 14-bit high-speed digital-to-analog converter (DAC), a 276-kHz analog low-pass filter (LPF), a TX attenuator, and an echo-cancellation (EC) channel. The RX channel of TLV320AD13A consists of a 1.104-MHz digital LPF, a 1.104-MHz analog LPF, a frequency equalizer, and a programmable-gain amplifier (PGA). The clock circuit divides a 35.328-MHz frequency from an external voltage controlled oscillator (VCXO) down to the necessary frequencies used throughout the device. The frequency of the external VCXO of TLV320AD13A is controlled by a 12-bit onboard voltage-output DAC. An onboard reference circuit generates a 1.5-V reference for the converters.

The TLV320AD13A 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 host transceiver such as the TI C6x DSP. Configuration is done via a serial port. The TLV320AD13A 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 TLV320AD13A codec is characterized for operation in the temperature range of 40°C to 85°C and is available in a 100-pin PQFP (PZ) package.
