The microprocessor TC9307AF-008 has all functions of the DTS, this means the TC9307AF-008 has the 130MHz prescaler, PLL frequency synthesizer and the LCD driver. If TC9307AF-008 combined with the TD6135AP prescaler, they can receive TV's (VHF, UHF) all channel programs. The digital tuning system which is formed by this IC has the following main functions: (1)Manual up/down tuning, auto scan tuning, fast tuning and automatic storage tuning. (2)Can preset 20 radio frequencies and the last radio frequency you have heard. (3)Clock display with I2h/24h and TIMER function, sleep function. 1.Circuit block diagram and pin functions of the TC9307AF-008: Figure1. Circuit block diagram and pin functions of the TC9307AF-008.
