Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Use appropriate ESD precautions. Meets class 1 ESD test requirements, (human body model HBM), in accor-
dance with MIL-STD-883C, method 3015. Do not operate or store near strong electrostatic fields.
Sensitivity is defined as the average signal level measured at the input necessary to achieve 10
-2
BER (bit error rate). The input signal is
defined as a return-to-zero (RZ) waveform with 50% average duty cycle (Manchester encoded data) at a data rate of 300b/s. The RF input is
assumed to be matched into 50
.
Spurious reverse isolation represents the spurious components which appear on the RF input pin (ANT) measured into 50
with an input RF
matching network.
Sensitivity, a commonly specified receiver parameter, provides an indication of the receiver
’
s input referred noise, generally input thermal
noise. However, it is possible for a more sensitive receiver to exhibit range performance no better than that of a less sensitive receiver if the
background noise is appreciably higher than the thermal noise. Background noise refers to other interfering signals, such as FM radio
stations, pagers, etc.
A better indicator of achievable receiver range performance is usually given by its selectivity, often stated as intermediate frequency (IF) or
radio frequency (RF) bandwidth, depending on receiver topology. Selectivity is a measure of the rejection by the receiver of
“
ether
”
noise.
More selective receivers will almost invariably provide better range. Only when the receiver selectivity is so high that most of the noise on the
receiver input is actually thermal will the receiver demonstrate sensitivity-limited performance.
Parameter scales linearly with reference oscillator frequency f
T
. For any reference oscillator frequency other than 4.90MHz, compute new
parameter value as the ratio:
f
MHz
4.90
Example: For reference oscillator freqency f
T
= 6.00MHz:
6.00
4.90
Parameter scales inversely with reference oscillator frequency f
T
. For any reference oscillator frequency other than 4.90MHz, compute new
parameter value as the ratio:
4.90
f
MHz
REFOSC
Example: For reference oscillator frequency f
T
= 6.00MHz:
4.90
6.00
Demodulator filter bandwidths are related in a binary manner, so any of the (lower) nominal filter values may be derived simply by dividing this
parameter value by 2, 4, or 8 as desired.
