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.
