5V Description

Short technical summary and product information.

The Texas Instruments AFE1302 is an Analog Front-End (AFE) IC designed to reduce the size and cost of ADSL-compliant systems. It provides the active analog circuitry necessary to interface an ADSL Digital Signal Processor (DSP) with external components like line drivers, receivers, filters, and transformers.

This device supports downstream data rates of 4Mbps and higher, operating at a clock rate of 35.328MHz with an output word rate up to 8.832MWords/s. The AFE1302 features a low noise floor of -144 dBm/Hz and consumes only 570mW of power. It includes a transmit (TX) channel for buffering outgoing DMT data and a receive (RX) channel for amplifying, filtering, and digitizing incoming DMT data.

The AFE1302 operates on a single 5V supply, with digital circuitry supporting voltages from 3.3V to 5V. The RX channel incorporates a low-noise PGA and a delta-sigma Analog-to-Digital Converter (ADC) producing a 16-bit output. The TX channel includes a fourth-order delta-sigma Digital-to-Analog Converter (DAC), a switched-capacitor low-pass filter, and a programmable attenuator.

Packaged in a TQFP-48, the AFE1302 is designed for integration into ADSL systems requiring efficient analog signal processing. It is intended for use with external amplifiers and filters to enhance noise reduction and dynamic range.
