Product Description

2.1 Overview

The IC is a very low power consumption single chip ASK Superheterodyne

Receiver (SHR) for the frequency band 390MHz. The SHR offers a high level

of integration and needs only a few external components. The device contains

a low noise amplifier (LNA), a double balanced mixer, a fully integrated VCO, a

PLL synthesiser, a crystal oscillator, a limiter with RSSI generator, a data filter,

a data comparator (slicer) and a peak detector. Additionally there is a power

down feature to save battery life.

2.2 Application

Keyless Entry Systems

Remote Control Systems

Fire Alarm Systems

Low Bitrate Communication Systems
