CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
Notes:
1. Unless noted otherwise, specifications apply over the entire specified operating temperature and voltage ranges.
2. One or more of the following United States patents apply: 4,454,488; 4,616,197; 4,749,964; 4,902,925. Other patents are pending.
3. Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the
equipment manufacturer.
4. The design, manufacturing process, and specifications of this device are subject to change without notice.
5. A variety of on-off-keyed(OOK) pulse modulation schemes are possible since digital decoding is an external function (not included in
the ASH receiver).
6. These parameters apply over the absolute minimum operating passband which is referenced to f
C
.
7. With interfering signal matched to the receiver modulation and code. See “Typical Modulated Interference Rejection” for a more
detailed view.
8. Sample repetition rates greater than 1 MHz are available in custom versions. Contact RFM for details.
9. Baseband bandwidths and data rates are available to 140 kHz and 56 kHz, respectively, in custom versions. Contact RFM for
details.
10. The default comparator threshold (with terminal 5 not connected) is optimized for low duty-cycle, or “bursty” data and eliminates
noise output when there is no RF signal. The override threshold (with terminal 5 connected to ground) is optimized for continuous
data.
11. The ASH receiver is designed to drive a single CMOS load.
12. For ESD protection.
