Continued from preceding page.
Outputs various information for easy system configuration.
Outputs DTS-CD/LD detection flag for 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 transition period signal at VCO clock and oscillation amplifier clock switch.
Outputs of channel status bit 1 (non-PCM data detection bit).
Outputs channel status emphasis information.
Outputs first 48 channel status bits update flag.
Validity flag and user data output can also be selected.
Various settings and outputs can also possible through microcontroller interface.
Large number of built-in functions to reduce number of peripheral circuit.
Built-in modulation function that can attach channel status, validity flag, and user data.
Total of 7 digital data input pins: 1 input pin with amplifier and 6 input pins with 5V input level tolerable can be
acceptable TTL level signal.
Bi-phase input data detection function that enables monitoring with input pin status microcontroller.
Input data can be selected via PLL lock error.
Input data can be selected independently from the selection of demodulation data from the 8 types of input data.
2 types of bit clock and LR clock outputs are provided. Various divide ratios can be set for one of these types.
A serial digital audio data input pin is provided. It can be switched to demodulation output.
Data input to the serial digital audio data input pin can be modulated.
Built-in oscillation amplifier and frequency divider for crystal resonator can also be used as clock generator.
Built-in 4 bit general-purpose parallel I/O port can also be used for interface with peripheral IC.
Single 3.3V power supply operation. TTL input port supports 5V interface.
Small SQFP48 package for efficient substrate mounting surface use.
