1. Typical sensitivity data is based on a 10 bit error rate (BER), using DC-balanced data. There are two test methods commonly used to measure
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
data and receiver current are given at 2.4 kbps for both high sensitivity operation (R = 330 K) and low current operation (R = 1100 K).

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.
