ST70134 is a fully integrated CPE ADSL AFE featuring 12 bit resolution, 1.1MHz signal bandwidth in Rx, 8.8MS/s ADC, 8.8MS/s DAC, -60dB THD, 4-bit digital interface to/from the DMT modem, 1V full scale input, differential analog I/O, accurate continuous-time channel filtering, 3rd & 4th order tunable continuous time LP filters, 0.5 watt at 3.3V, 0.5mm HCMOS5 LA technology and 64 pin TQFP package
The ST70134 is an Analog Front End (AFE) designed for the STMicroelectronics ASCOT™ ADSL chipset. When coupled with a DMT modem like the ST70135A or ST70235, it provides a T1.413 Issue 2 or G.dmt compliant solution. The device handles two transmission channels on a balanced 2-wire interconnection, supporting upstream rates from 16 to 640Kbit/s and downstream rates up to 8.192Mbit/s.
