Notes:

OOK/ASK receiver sensitivity, the “100% AM” test method and the “Pulse” test method. Sensitivity data is given for both test methods. See Ap-

pendix 3.8 in the ASH Transceiver Designer’s Guide for the details of each test method, and for sensitivity curves for a 2.2 to 3.7 V supply voltage

range at five operating temperatures. The application/test circuit and component values are shown on the next page and in the Designer’s Guide.

2. At low data rates it is possible to adjust the ASH pulse generator to trade-off some receiver sensitivity for lower operating current. Sensitivity

3. Data is given with the ASH radio matched to a 50 ohm load. Matching component values are given on the next page.

4. See Table 1 on Page 8 for additional information on ASH radio event timing.
