TELEFUNKEN Semiconductors

Low-Current Superhet Remote Control Receiver

Description

The U4313B 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 less than 1 mA total current

modulated mode. Typical applications are keyless car consumption, 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

Inverting clamping comparator with amplitude-

depending hysteresis for data regeneration
