| DATA SHEET Part No. Package Code No. AN5832SA SSOP032 - P - 0300AP SEMICONDUCTOR COMPANY MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD. Publication date: February 2005 SDB00096AEB 1 AN5832SA Contents Features ............................................................................................................................. 3 Applications ........................................................................................................................ 3 Package ............................................................................................................................ 3 Application Circuit ................................................................................................................ 4 Block Diagram ...................................................................................................................... 6 Pin Descriptions ..................................................................................................................... 7 Absolute Maximum Ratings .................................................................................................... 8 Operating Supply Voltage Range ............................................................................................. 8 SDB00096AEB 2 AN5832SA AN5832SA Silicon Monolithic Bipolar IC Features Supports both I2C bus and parallel control Integrated SIF demodulation Fully adjustment - free ( when used with SIF input ) 2 adjustment points when used with baseband input Integrated voice AGC circuit Reduced peripheral component count Low power consumption ( typ. VCC = 5 V, ITOT = 28 mA ) Near pin to pin compatible with AN5833SA ( Japanese TV audio multiplex demodulation IC ) Applications TV sets, VCRs, DVD recorders, PCs, car navigation systems, and similar products for US market Package DIL-32PIN Plastic Package (SO Type) SDB00096AEB 3 AN5832SA Application Circuit < Instructions of Application Circuits > 1 ) In case of using base band input, ICs were adjusted to perform good separation when input level ismatched with 100 mV[rms] ( = 283 mV[p-p] ) on condition of mono 100% mod pre-emphasis OFF. However, if good enough separation can't be taken in the cause of un-matching frequency characteristic and so in input signal, it can adjust separation by connecting a volume between #22Pin and GND for adjusting high frequency separation. If it not need adjusting separation, please open #22Pin. If it need adjusting low frequency separation also, please adjust the input level volume for taking best separation on low frequency. 2 ) In case of using SIF input, please set up the SIF input level from tuners between 80 dBV to 110 dBV in standard RF input conditions. Please select SIF - BPFs that group delay of 4.5 MHz 42 kHz is flat as possible. 3 ) In measuring characteristics of separation, please use the stereo modulator that perform good characteristic on dbx encoder and corrected well. In case of using SIF input, please correct FM modulation band to 25 kHz exactly at mono 100% mod pre-emphasis OFF with the 0 carrier method. And, please use LPFs that reduce 30 kHz signal over 20 dB setting between line-outs and AB level meter SDB00096AEB 4 AN5832SA Application Circuit ( continued ) ( 1 ) Example of No Adjustments Application Circuits in case of SIF Input ( 2 ) Example of Adjustments Application Circuits in case of Base Band Input SDB00096AEB 5 AN5832SA Block Diagram SDB00096AEB 6 AN5832SA Pin Descriptions Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 N.
