TRENDCHIP原装现货:TC3085-TQ64-EPG

TC3085 ADSL2/2+ *og 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 Di*al 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 di*al-to-*og converter (DAC), *og-to-di*al converter (ADC), di*al
controller oscillator (DCXO), line driver and filters, RX programmable gain/attenuation (PGA) and filters,
and di*al 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 p* filter. The received path consists
of programmable low noise preamplifiers, filters, and a 14-bit linear ADC.
