8M TO 1.
1MWords/s WORD RATE q FIVE GENERAL-PURPOSE OUTPUTS q 570mW POWER DISSIPATION q TQFP-48 PACKAGE DESCRIPTION Burr-Brown’s Analog Front-End from Texas Instruments reduces the size and cost of an ADSL-compliant system by providing the active analog circuitry needed to connect an ADSL Digital Signal Processor (DSP) to an external line driver, receiver, TX/RX filters, hybrid, transformer, and POTS filter.
The AFE1302 is designed for downstream data rates of 4Mbps and higher, and operation at a clock rate of 35.
328MHz, with an output word rate of up to 8.
832MWords/s.
Functionally, this unit consists of a transmit (TX) channel, a receive (RX) channel, a VCXO (Voltage Controlled Crystal Oscillator) control Digital-to-Analog Converter (DAC), and VCXO active circuitry.
The TX section converts, filters, and buffers outgoing Discrete Multi Tone (DMT) da...
