U4311B
Low-Current Superhet Remote Control Receiver
Description
The U4311B is a monolithic integrated circuit in bipolar
technology for low-current UHF remote control super-
heterodyne receivers in amplitude- or frequency-
modulated mode. Typical applications are keyless car
lock-, alarm- or tele-control remote indication systems.
Especially for automotive applications, it supports a
superhet design with about 1 mA total current
consumption as required by the car manufacturers.
Features
D Usable for amplitude- and frequency-modulated
transmission systems
D Extremely low quiescent current (approximately
1 mA in standby mode due to wake-up concept)
D Wide power supply voltage range 3 to 13 V
D Sensitive IF amplifier for 10.7-MHz operating
frequency
D Logarithmic AM demodulator
D FM demodulator
D Monoflop exit to wake up a microcontroller
D High-performance operational amplifier to realize a
data recovering filter
D Non-inverting clamping comparator with amplitude-
depending hysteresis for data regeneration
