Single-Chip DTS Microcontroller (DTS-20)
TC9324F
The TC9324F is a single-chip digital tuning system (DTS)
microcontroller incorporating a 230 MHz prescaler, PLL, and
LCD driver. In addition to a 20-bit IF counter, an 8-channel, 8-bit
AD converter, two types of serial interface, and buzzer function,
the TC9324F offers a range of functions required for DTS,
including an interrupt function, an 8-bit timer-counter, and an
8-bit pulse counter. In addition, the LCD driver features six
modes combining 1/4, 1/3, and 1/2 duty and 1/2 and 1/3 bias. This
product is suitable for use in a wide variety of DTS systems, from
automobile to home audio, including compact stereo systems.
