Receiver/Data Demodulator
Preliminary Information
General Description
The MICRF011, an enhanced version of the MICRF001, is a single chip
OOK (ON-OFF Keyed) Receiver IC for remote wireless applications,
employing Micrel’s latest QwikRadio
technology. This device is a true
“antenna-in, data-out” monolithic device. All RF and IF tuning is
accomplished automatically within the IC, which eliminates manual
tuning and reduces production costs. Receiver functions are completely
integrated. The result is a highly reliable yet extremely low cost solution
for high volume wireless applications. Because the MICRF011 is a true
single-chip radio receiver, it is extremely easy to apply, minimizing design
and production costs, and improving time to market.
The MICRF011 is a functional and pin equivalent upgrade to the
MICRF001, providing improved range, lower power consumption, and
higher data rate support when in FIXED mode.
The MICRF011 provides two fundamental modes of operation, FIXED
and SWP. In FIXED mode, the device functions like a conventional
superheterodyne receiver, with an (internal) local oscillator fixed at a
single frequency based on an external reference crystal or clock. As with
any conventional superheterodyne receiver, the
transmit
frequency must
be accurately controlled, generally with a crystal or SAW (Surface
Acoustic Wave) resonator.
In SWP mode, the MICRF011 sweeps the (internal) local oscillator at
rates greater than the baseband data rate. This effectively “broadens”
the RF bandwidth of the receiver to a value equivalent to conventional
super-regenerative receivers. Thus the MICRF011 can operate with less
expensive LC transmitters without additional components or tuning, even
though the receiver topology is still superheterodyne. In this mode the
reference crystal can be replaced with a less expensive
±
0.5% ceramic
resonator.
All post-detection (demodulator) data filtering is provided on the
MICRF011, so no external filters need to be designed. Any one of four
filter bandwidths may be selected externally by the user. Bandwidths
range in binary steps, from 0.625kHz to 5kHz (SWP mode) or 1.25kHz to
10kHz (FIXED mode). The user only needs to program the appropriate
filter selection based on data rate and code modulation format.

IMPORTANT: Items in bold type represent changes from
the MICRF001 specification. Differences between the
MICRF001 and -011 are identified in table 2, together with
design considerations for using the -011 in present
MICRF001 designs.
