Data Sheet

General Descriptions

TC3085 ADSL2/2+ analog front-end is a high performance CMOS device that provides a complete

solution for the front-end requirements of ADSL, ADSL2 and ADSL2+. This level of functionality was

previously available only with multiple devices. TC3085 is designed for Asymmetrical Digital Subscriber

Line Customer Premises Equipment (ADSL CPE). It support all ADSL standards (ADSL1/2/2+), including

Annex A, B, I, J & M.

TC3085 integrates the digital-to-analog converter (DAC), analog-to-digital converter (ADC), digital

controller oscillator (DCXO), line driver and filters, RX programmable gain/attenuation (PGA) and filters,

and digital interface. TC3085 features a highly integrated signal path with advanced on-chip-filtering. A

13-bit linear DAC precedes the fully integrated line driver, and low pass filter. The received path consists

of programmable low noise preamplifiers, filters, and a 14-bit linear ADC.
