INTRODUCTION
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 filter-
ing 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.
The AFE receive path contains a programmable
gain amplifier (RxPGA), a low pass anti-aliasing
filter, and a 12-bit A/D converter. The RxPGA is
digitally programmable from 0 to 31dB in 1dB
steps.
The AFE transmit path consists of a 14-bit D/A
converter, followed by a programmable gain
amplifier (TxPGA). The transmit gain is program-
mable from 0 to -15dB in 1dB steps.
