2.2 Outputs various information to make system configuration easy

• Outputs DTS-CD/LD detection flag by DTS sync signal detection.

• Outputs burst preamble Pc from microcontroller interface.

• Calculates sampling frequency of input signal and outputs it from microcontroller interface.

• Outputs interrupt signal for microcontroller (interrupt source can be selected).

• Outputs signal of transitional period switching between VCO clock and oscillation amplifier clock.

• Outputs bit 1 of channel status (non-PCM data detection bit).

• Outputs emphasis information of channel status.

• Outputs renewed flag of the first 48 bits channel status.

• Channel status bit, validity flag and user data output are selectable.

• Outputs modulation/demodulation preamble B information.

• Possible to carry out and output various settings through microcontroller interface.

2.3 Plenty of built-in functions to reduce peripheral circuits

• Includes modulation function that can attach channel status, validity flag, and user data.

• Equipped with a total of 7 digital data input pins: 1 input pin with an amplifier and 6 input pins with 5V tolerable

TTL level signal.

• Possible to monitor input pin status with microcontroller by mounting a bi-phase input data detection function.

• Possible to select input data among 8 system input data including modulation function output.

• Possible to select output of input-data through among 8 system input data aside from selecting demodulation data.

• Includes 2 system bit clock and LR clock outputs. Various frequency-dividing ratios can be set to one of these two

systems.

• Equipped with a serial digital audio data input pin. Possible to switch with demodulation output.

• Possible to modulate the data that is input to the serial digital audio data input pin.

• Includes built-in oscillation amplifier and frequency divider for quartz resonator and also possible to use them as

clock generator.

• Includes 4 bits general-purpose parallel I/O port. It can be used for interface with peripheral ICs.

• All the channel status can be decoded through peripheral circuit using preamble B information.

• A continuous switching operation between external clock synchronous mode and PLL clock synchronous mode is

possible.

• Single 3.3V-power supply operation. TTL input port supports 5V interface.

• Adopts small SQFP48 package for efficient use of substrate mounting area.
