ABSTRACT:
An asymmetric digital subscriber line (ADSL) transceiver chip is provided that includes a single integrated circuit (IC) substrate to host the circuit and an analog front-end (AFE) configured to receive and transmit analog signals. The AFE has a dynamic range greater than about 85dB and the received analog signals have bandwidths of about 2 mega-hertz. The ADSL chip also includes a digital signal processor (DSP) configured for digital processing and including bypass capacitors configured to provide switching charge. The AFE and the DSP are formed on the single IC substrate.
