DESCRIPTION

The SLIC KIT (L3000N/L3092) is a set of solid state devices designed to integrate many of the functions needed to interface a telephone line. It consists of 2 integrated devices ; the L3000N line interface circuit and the L3092 control unit.

■ PROGRAMMABLE DC FEED RESISTANCE AND LIMITING CURRENT (25/40/60mA)

■ LOW ON-HOOK POWER DISSIPATION (50mW typ)

■ SIGNALLING FUNCTION (off-hook/GND-Key)

■ QUICK OFF-HOOK DETECTION IN CVS FOR LOW DISTORTION (< 1 ) DIAL PULSE DETECTION

■ HYBRID FUNCTION

■ RINGING GENERATION WITH QUASI ZERO OUTPUT IMPEDANCE, ZERO CROSSING INJECTION (no ext. relay needed) AND RING TRIP DETECTION

■ ABSOLUTELY NO NOISE INJECTED ON ADIACENT LINES DURING RINGING SEQUENCE

■ AUTOMATIC RINGING STOP WHEN OFFHOOK IS DETECTED

■ TEST MODE ALLOWS LINE LENGHT MEASUREMENT

■ PARALLEL LATCHED DIGITAL INTERFACE

■ LOW NUMBER OF EXTERNAL COMPONENTS WITH STANDARD TOLERANCE ONLY : 9 1 RESISTORS AND 5 10-20 CAPACITORS (for 600 ohm appl.)

■ POSSIBILITY TO WORK ALSO WITH HIGH COMMON MODE CURRENTS

■ GOOD REJECTION OF THE NOISE ON BATTERY VOLTAGE (20dB at 10Hz ; 35dB at 1KHz)

■ INTEGRATED THERMAL PROTECTION

■ SURFACE MOUNT PACKAGE (PLCC28 + PowerSO-20)

■ 0°C TO 70°C: L3000N/L3092

■ -40°C TO +85°C: L3000NT/L3092T
