| 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. Device implements signal reception in FM, MW bands of world standard and LW band of European standard (Table 1) ORDERING INFORMATION IND1723Q PLASTIC TA = -20 TO 70 C FOR PACKAGE Channel spacing,kHz 50 9 1 50 9 1 100 10 200 10 200 10 100 9 100 9 100 5 Reference frequency,kHz 25 9 1 25 9 1 25 10 25 10 25 10 25 9 25 9 25 5 Intermediate frequency,kHz 10700 450 450 10700 459 459 10700 450 10700 450 10700 450 10700 450 -10700 450 10700 450 Region FM MW LW FM MW LW FM MW FM MW FM MW FM MW FM MW FM MW Europe1 Europe 2 USA 1 USA 2 USA 3 The Near East and the Middle East Japan Central and South America Receiving frequency 87.5-108.0 MHz 522-1620 kHz 144-290 kHz 87.5-108.0 MHz 522-1620 kHz 144-290 kHz 87.5-108.0 MHz 530-1620 kHz 87.5-107.9 MHz 530-1620 kHz 87.5-107.9 MHz 530-1710 kHz 87.5-108.0 MHz 531-1602 kHz 76.0-90.0 MHz 522-1629 kHz 87.5-108.0 MHz 520-1620 kHz It is possible to change band by changing ROM option. *Device allows to select modes: manual tuning (search, scanning), station holding and by memory scanning. *By means of 6 button it is possible to store 18 stations in FM band (6 stations in each FM1, FM2, FM3) 12 stations in MW band (6 stations in each MW1, MW2), 6 stations in LW and also VF band. *IC has LAST CHANEL MEMORI function (memory of last channel): FM-3, MW-2, LW-1, VF-1. *Opportunity to implement automatic search of VF station (movement information and so on). *Automatic station storing function. *Device implements holding of stations recorded in memory while receiver is turned-off. *Indication and control of MONO, LOC (search mode), stereo ST, tape type indication (MTL). *CD indication. *LOUD indication and control. *Watch function (12 hours and 24 hours modes) with turn-off watch opportunity. *In-chip up to 200MHz frequency display scale circuit (Vin=0.3V), intermediate frequency counter, ADC,LCD driver. *Keypad data input port. *One power supply 5V 10% *Supply current MAX 21mA (in FM mode) 0 0 *Operating ambient tempetature -20 - +70 C *Quartz reference frequency 4.5MHz *CMOS process 1 IND1723Q FM3 VF SK ST MONO LOC LOUD MTL RDMONI FM1 FM2 50 MW DKSTBY LW NR1 NR2 AMS AM PM CH 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 IND1723Q +9B 10K 0 022 SD ST 4 7K +9B 32 31 30 29 28 27 26 25 24 23 22 21 20 30 22 4.5MHz POWER NR1 MTL AMS +5B + 100 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 U(FMVCO) 8 2K 01 + 3 3 1 8K STU 01 01 +12B 10K KTC3199Yx2 4 7K + 47K 0 022 0 01 0 01 0 01 0 01 0 022 1 2K 3 3 1 2K FMVCO AMVCO LOUD MONO/NR2 FMIF AMIF AMUTE RDMUTE BAND2 BAND1 MODE LOC AGCC U(AMVCO) 0 022 KTC3199Yx2 2 |
