CXA2013M
EIAJ Sound Multiplexing Decoder
Description The CXA2013M is a bipolar IC designed as EIAJ TV sound multiplexing decoder, provides various functions including sound multiplexing demodulation, broadcast mode identification (stereo/bilingual discrimination display), volume, tone control and muting. Features * Adjustment free of filter * Audio multiplexing decoder * Sound processor -- One external input -- Bass control -- Treble control -- Volume control -- Balance control are all included in a single chip. Almost any sort of signal processing is possible through this IC. * Separation adjustment, each mode control and sound processor control are possible through I2C BUS.

Description of Operation The sound mutiplexing signal input from Pin 5 is passed through IN AMP and is applied to the Cue BPF, Sub BPF, and Main de-emphasis circuit. 1. Discrimination circuits Cue BPF passes only the Cue signal component from the multiplex signal. In the AM demodulator, the signal (AM wave) is AM detected and one of two sine waves is generated, either a 922.5Hz signal for bilingual broadcasts or a 982.5Hz signal for stereo broadcasts. In the 952Hz BPF, the 3.5fH carrier component is eliminated from the Cue signal after AM wave detection. The Cue signal, from which the carrier component has been eliminated, is waveform shaped by COMP with , the resulting 922.5Hz or 982.5Hz pulse being applied to the Logic section. In the 3.5fH VCO, a 3.5fH pulse locked onto the Cue signal carrier (3.5fH) is created and sent to the Logic section. In the Logic section, the broadcast mode is identified using the countdown method. Depending on this result as well as the presence of a SUB signal from SUB detector and the MUTE ON/OFF, MODE switching, and FOMO ON/OFF instructions from CONT, the output switching control signal is created. This signal is used to control the output condition of OUTPUT SW and MAIN OUT. 2. Main circuits In MAIN DEEM, de-emphasis is applied to the Main signal component and the Sub and Cue components are removed. After passing through the MAIN DEEM, the Main signal is applied to MATRIX, OUTPUT AMP, and MAINOUT. 3. Sub circuits In SUB BPF, only the SUB signal component out of multiplex signals is passed through. In the 4.5fH trap, the digital facsimile signal component is removed. In FM Demod, the SUB signal is FM demodulated. In SUB DEEM, the FM demodulated Sub signal is de-emphasized and the carrier component is removed. After passing through SUB DEEM, the Sub signal is applied to MATRIX and OUTPUT AMP. 4. MATRIX and output circuits In MATRIX, the L and R signals are created by adding and subtracting the Main signal from MAIN DEEM and the Sub signal from SUB DEEM in stereo broadcast. In OUTPUT AMP and OUTPUT SW, the output signal is switched under the control of Logic. In addition, MAIN OUT always outputs the MAIN signal component, regardless of the broadcast mode. 5. TONE circuit Control BASS and TREBLE. Bass and TREBLE characteristics are decided by each CL and CH external capacitance. 6. BALANCE, VOLUME curcuit Control BALANCE and VOLUME. BALANCE has 64steps and VOLUME has 256 steps. 7. DAC DAC is the circuit that control BASS, TREBLE, VOLUME and BALANCE. Internal impedance is approximately 20k (approximately 5k for VOLUME). Connect the external capacitance for LPF to each pins. - 16 -

I2C Bus Signal There are I2C signals, SDA (Serial DATA) and SCL (Serial CLOCK) signals. SDA is a bidirectional signal. * Accordingly there are 3 values outputs, H, L, and Hi-Z.
