IL2533 General Description
IL2533N, IL2533D is CMOS IC, supporting all functions, necessary for design of electronic telephone with high characteristics. Standard application circuit is shown at figure 2.
Device includes LD/MF constant automatic dialer, melodies generation, ring frequency identification and high quality circuit for line/speech.
RAM at chip, intended for redialing of 31-digit number and memory elements, containing upto 21 symbols/data. Floating marker method enables to use LNR function under control of different systems. Device contains volume control of hearing aid. Volume is controlled by VOL button (5.4dB) or "/+" button (plus 8.1/minus 5.4dB in 5 levels).
IL2533 Features
` Line/speech circuit. LD/MF constant automatic dialer and tone ring at one 28-pin CMOS chip.
` Operational range 13 to 100 m (decreasing upto 5 m causes productivity deterioration).
` Soft limitation for elimination of drastic distortion.
` Controlling of received signal volume.
` Automatic line loss compensation.
` Low noise level (max 72 dBmp).
` Actual or complex impedance.
` Switching LD/MF dialing.
` Tone damper during programming.
` Redial of the last 31 digit number.
` Reference storage.
` Redial of busy line or previous connection.
` Pause button for applying to pause or waiting function.
` 3 pulse flashes: buttons, "R1"100 ms, "R2" 280 ms and "R3" 375/600 ms.
` Active RC-filter on chip.
` Circuit of ring frequency determination.
` Three-tone melody generator
