The Texas Instruments AFE1302 is an Analog Front-End (AFE) integrated circuit 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 IC is suitable for downstream data rates of 4Mbps and higher, operating at a clock rate of 35.328MHz. Key electrical specifications include a noise floor of -144 dBm/Hz and a maximum output word rate of 8.832 MWords/s with 16-bit resolution. The receive channel features a low-noise PGA and a delta-sigma Analog-to-Digital Converter (ADC), while the transmit channel includes a delta-sigma Digital-to-Analog Converter (DAC) and a programmable attenuator.
The AFE1302 operates on a single 5V supply, with digital circuitry supporting voltages from 3.3V to 5V. It consumes only 570mW of power. The device is housed in a TQFP-48 package, designed for surface mounting.
This AFE is intended for use with external amplifiers and filters to enhance noise reduction and dynamic range, making it a versatile component for ADSL applications.
