U4311B

TELEFUNKEN Semiconductors

Low–Current Superhet Remote Control Receiver

Description

The U4311B is a monolithic Integrated Circuit in bipolar lock-, alarm or telecontrol remote indication systems.

technology for low-current UHF remote control super- Especially for automotive applications it supports a

heterodyne receivers in amplitude- or frequency- superhet design with about 1 mA total current consump-

modulated mode. Typical applications are keyless car tion, as required by the car manufacturers.

Features

Usable for amplitude- and frequency- modulated

transmission systems

Logarithmic AM demodulator

FM demodulator

Extremely low quiescent current approximately 1 mA

in the stand-by mode due to wake-up concept

Monoflop exit to wake up a microcontroller

High performance operational amplifier to realize a

data recovering filter

Wide power supply voltage range 3 to 13 V

Sensitive IF-amplifier for 10.7 MHz operating

frequency

Non-inverting clamping comparator with amplitude-

depending hysteresis for data regeneration
