SHAOXING SILICORE TECHNOLOGY CO.,LTD www. Silicore. com. cn CHMC 2.4W AUDIO AMPLIFIER, SIF AMPLIFIER AND DETECTOR FOR TV SILICON MONOLITHIC BIPOLAR INTEGRATED DIRCUIT CD1353CP D E S C R I P T I O N O u t l i n e D r a w i n g The CD1353CP is a silicon monolithic integrated circuit designed for SIF and Audio section in television receivers. This IC has all functions including sound IF Amplifier, FM Detector, DC volume control circuit, Audio Output amplifier with 2.4W output power and voltage regulator. This IC is encapsulated in 14pin dual in-line package with heat tab. F E A T U R E S : z All functions for SIF and audio stage are provided by this one-chip IC and this IC will realize reduction of assembly cost as well as reduction of number of other components. z Audio output power is controlled by electronic attenuation circuit which operate at DC. Therefore, unnecessary radiation, oscillation etc. are eliminated. Due to DC control, shielded wire is not required and variable resistor will be placed anywhere required. z Electronic attenuator has enough attenu ation (Typ.80dB) by the adoption of squelch circuit. In addition, as attenuation characteristic is same with resistance change of variable resistor, suitable variable resistor will be selected easily. z As Peak differential detection method is adopted for FM detection, outside circuitry can be very simple easy. z As operation voltage (Vcc) range for output stage is very wide (9-18V), suitable Vcc can be freely determined for required output level.
