3 GENERAL DESCRIPTION

HITAG(1) is the family name of the reader chip

HTRC11001T to use with transponders which are based

on the HITAG tag ICs (HT1ICS3002x or HT2ICS2002x).

(1) HITAG - is a trademark of Philips Semiconductors

Gratkorn GmbH.

The receiver parameters (gain factors and filter cut-off

frequencies) can be optimized to system and transponder

requirements. The HTRC11001T is designed for easy

integration into RF identification readers.

State-of-the-art technology allows almost complete

integration of the necessary building blocks. A powerful

antenna demodulator and driver, together with a low-noise

adaptive sampling time demodulator, a programmable

filter, amplifier and digitizer, build the complete transceiver

unit, required to design high-performance readers.

A three-pin microcontroller interface is employed for

programming the HTRC11001T as well as for the

bidirectional communication with the transponders. The

three-wire interface can be changed into a two-wire

interface by connecting the data input and the data output.

Tolerance dependent zero amplitude modulation will

cause severe problems in envelope detector systems,

resulting in the need of very low tolerance reader

antennas. These problems are solved by the new Adaptive

Sampling Time (AST) technique.
