CXA2202M
EIAJ Sound Multiplexing Decoder
Description The CXA2202M, 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), mode display, and muting. Features * Adjustment free of filter * High frequency stereo separation improved * An internal active filter greatly reduces the external parts * Use of the countdown method for broadcast mode identification eliminates the necessity of adjusting the identification system (Cue oscillator) * Internal filter eliminates interference from digital facsimile signals * The discrimination time needed to shift from multiplexing sound to monaural sound is reduced. * Output level: 520mVrms (1kHz, monaural, 100%) * Forced monaural mode can be set to operate only for stereo broadcasts or for stereo/bilingual broadcasts. Applications * Color TVs * Hi-Fi VCRs Pin Configuration

CXA2202M
Description of Operation The sound mutiplexing signal input from Pin 7 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.

Switch Procedure 1) Connect components as shown in figure above. (Set SW4 to NORM.) 2) Set the encoder to stereo mode, and input a 100% modulated 1kHz signal; also set the encoder so that only the L-ch is output. 3) Monitor the oscilloscope and AC voltmeter and adjust VR2 so that the R-ch is at a minimum.
