IND1723Q CONTROLLER AND FREQUENCY SYNTHESIZER USED IN AUTOMOBILE RECEIVER WITH FM, MW,LW BAND This device is functionally identical to the mPD1723. This integrated circuit is a CMOS LSI circuit developed for use in FM,MW,LW receivers. It is manufactured in 64-lead PQFP (Plastic Quad Flat Package). In-chip controller, Phase-Locked Loop (PLL) Frequency Syn the sizes, watch, up to 200MHz frequency display scale, intermediate frequency counter , analog-to-digital converter (ADC), liquid-crystal display (LCD) driver all reduce sizes of high quality FM, MW,LW receivers, used in cars of high class. Characteristics.
