Afatech AF9035

Afatech AF9035


AF9035 is integrated digital television USB-interface and DVB-T demodulator. Metal box on bottom-right direction from the AF9035 is 12.000 MHz clock source. Black 8 pin chip left from the clock source is 2k serial eeprom (24C02). It is used likely for storing USB ID and other hardware design settings.

Demodulator integrated that chip is AF9033 and it is sold separately too. AF9035 supports dual mode, which means it can feed two television stream at the same time. For dual configuration it is needed one RF-tuner more and 2nd demodulator which is AF9033. Chip needs firmware.

AF9015 is predecessor of that chip and IT9135 is successor.

ITE Tech has acquired Afatech in 2009. Chips starting from IT9135 are manufactured by ITE Tech.
