XE1201A 300-500 MHz

Low-Power UHF Transceiver

Features

General Description

The XE1201A is a half-duplex FSK transceiver for

operation in the 433 MHz ISM band (optimized) and in

the 300-500 MHz band. The modulation used is the

Continuous Phase, 2 level Frequency Shift Keying

(CPFSK). The direct conversion (zero IF) receiver

architecture enables on-chip channel filtering.

• very low-power

• half-duplex operation

• data rate up to 64 kbit/s

• high sensitivity

• few external components

• internal bit synchronizer

• 3-wire bus for easy microcontroller interface

• output power programmable via bus

The XE1201A includes a bit synchronizer so that glitch

free data with synchronized clock can directly be read by

a low cost / low complexity micro-controller. The

transmitted power level can also be controlled via the

bus. The XE1201A meets the I-ETS300-220 standard

and is available in a TQFP32 package.

Applications
