DESCRIPTION
CD1353CP Outline Drawing FEATURES
: z All function s for SIF and audio stage are provided by th is on e-chip IC and this IC will realize reduction of asse mb l y cost as well as reduction of nu mb er of o ther co mponents. z Audio outpu t po wer is controlled by electronic attenuation circuit which operate at DC. Therefore, unnecessary ra diation, oscillation etc. are eliminated . Due to DC control, shielded wire is not required and variable resistor will be placed anywhere required. z Electro nic attenu ato r h as en ou gh attenu ation (Typ.80dB) by the adoption of squelch circuit. In addition, as attenuatio n characteristic is same with resistance change of variable resistor, suitable variab le resistor will be selected easily. z As Peak differential detection method is adop ted for FM detection, outside circuitry can be very simp le easy. z As operation voltage (Vcc) range for output stage is very wide (9 -18V), suitable Vcc can be freely determined for required ou tput level.
