Functional Description
The block diagram illustrates the basic structure of the
MICRF001. Identified in the figure are the three principal
functional blocks of the IC, namely (1) UHF Downconverter,
(2) OOK Demodulator, and (3) Reference and Control. Also
shown in the figure are two capacitors (CTH, CAGC) and
one timing component (CR), usually a ceramic resonator.
With the exception of a supply decoupling capacitor, these
are all the external components needed with the MICRF001
to construct a complete UHF receiver. Three control inputs
are shown in the block diagram, SEL0, SEL1 and SWEN.
Through these logic inputs the user can control the operating
mode and programmable functions of the IC. These inputs
are CMOS compatible, and are pulled-up on the IC. The
inputs SEL0, SEL1 control the Demodulator filter bandwidth
in four binary steps from approximately 0.6kHz to 4.8kHz,
and the user must select the bandwidth appropriate to his
needs.
The SWEN pin allows the device to be configured in either its
normal (SWP) operating mode, or in standard (FIXED)
superheterodyne receiver mode. SWP operation is selected
when SWEN is HIGH, and is the default mode for the IC. An
example of SWP operation would be where the MICRF001
must operate with LC-based transmitters, whose transmit
frequency may vary up to ± 0.5% over initial tolerance, aging,
and temperature. In this (patent-pending) mode, the LO
frequency is varied in a prescribed fashion which results in
downconversion of all signals in a band 2-3% around the
transmit frequency. So the Transmitter may drift up to ±
0.5% without the need to retune the Receiver, and without
impacting system performance. Such performance is not
achieved with currently available crystal-based
superheterodyne receivers, which can operate only with
SAW or crystal based transmitters.
[Note: A range penalty will occur in installations where there
exists a competing signal of sufficient strength in this small
frequency band of 2-3%. This penalty also exists with super-
regenerative type receivers, as their RF bandwidth is also
generally 2-3%. So any application for a super-regenerative
receiver is also an application for the MICRF001.]
