description  
The TRF1400 VHF/UHF RZ ASK remote control  
receiver is specifically designed for RZ ASK  
(return-to-zero amplitude-shift keyed) commu-  
nications systems operating in the 200-MHz to  
450-MHz band. This device is targeted for use in  
automotive and home security systems, garage  
door openers, remote utility metering, and other  
low-power remote control and telemetry systems.

A complete RZ ASK receiver solution on a chip,  
the TRF1400 requires only a minimum of external  
components for operation. This significantly  
reduces the complexity and footprint of new  
designs compared with current discrete receiver  
designs. The TRF1400 requires no manual  
alignment when using external SAW (surface  
acoustic wave) filters. For a lower-cost solution,  
the device is also compatible with external LC  
components.

The TRF1400 also includes several on-chip features that normally require additional circuitry in a receiver  
system design. These include two low-noise front-end amplifiers, an RF amplifier/comparator for detection and  
shaping of input signals, and a demodulated RZ ASK baseband TTL-level output that readily interfaces to  
self-synchronizing devices. Also included is on-chip Manchester decoding logic that provides a specially  
formatted TTL data output, synchronized with a trigger output, for easy interface to any microcontroller using  
Manchester-encoded data.  
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.
