Description

The SD4001 is CMOS LSI chips developed for world-wide FM / MW / LW tuning with PLL frequency synthesizer system. The SD4001 can make a compac t and high performance FM / MW / LW tuner with clock function for high-end car stereo, home stereo and so on because these CMOS LSIs are in 64-pin QFP package with built-in PLL frequency sy nthesizer, controller, 200 MHz prescaler, LCD driver and IF counter. Functions Radio Functions (1) Manual tuning Manual tuning up/down ….. Stepped tuning an d rapid tuning. (2) Auto tuning Seek up/down ….. Retaining the frequency of a station received. Scan up/down ….. Receiving in intervals of 5 seconds. (3) Preset memory scanning ….. Receiving the contents of preset memories on the FM, MW. and LW bands for 5 seconds each. (4) VF auto – tuning SK seek up/down …. Retaining the frequency of a SK signal received. SK scan up/down …. Receiving a station with SK signal in intervals of 5 seconds. (5) Preset memories FM band …. FM 1:6 stations, RW 2:6 stations, FM 3:6 stations MW band … MW 1:6 stations, MW 2:6 stations L W band … 6 stations VF band …. 6 stations MW2 cannot be used while the LW band is used. (6) Last-preset memories …… 1 station on th e FM1, FM2, FM3, MW1, MW2, LW and VF bands each. (7) LOC (local) control signal outputs and indications. (8) FM MONO (monaural) control signal output and indication.(For VF bands, same as for FM) (9) “ST” (stereo) indicator …… Enabled on the FM and VF bands. (10) Auto-preset memories (11) DK stand-by and SK alarm function Tape Functions (1) Tape transport direction indictors ….. Can flash at 2 HZ during fast forward. (2) AMS (auto music search) control signal output and indication. (3) MTL (metal) control signal output and indication. (4) NR1 (noise reduction) and NR 2 control outputs and indications.

Functions (Continued) CLOCK Functions (1) Selectable 12-hour(with AM and PM indicators) of 24-hour display. (2) Selectable flashing colon(;) (1Hz) (3) Low-power (10 µA) backup available in the NOCLK(no-clock)mode. Others (1) LOUD (loudness) control sign al output and indication ….. co mmon to radio, tape and CD modes. (2) Key acknowledge(beep) signal outputs (2.25 kHz, 40ms) ….. Enabled by valid momentary keys. (3) Display selector and priority display function.
