The ST70136 ADSL Analog Front End (AFE) chip implements the analog transceiver functions required in a Customer Premise ADSL modem. It connects the digital modem chip with the loop driver and hybrid balance circuits. The AFE has been designed with high dynamic range in order to greatly reduce the external filtering requirements at the front end. The AFE chip and its companion digital chip along with a loop driver, implement the complete G.992.2 and G.992.1 DMT modem solution.
