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)

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.
