Notes
1. *CRITICAL* In order to operate the device over this range, it is necessary for a 200Ω resistor to be
2. Potential rate of data recovered on the DATA line (pin 10). The decoder rate is internally fixed at about
3. When operating from a 5V source, it is important to consider that the output will swing to well less than
4. V
5. For a BER of 10 -5 at 4,800 baud. Sensitivity is affected by the antenna’s SWR.
6. Time to valid data output.
7. Maximum drive capability of data outputs.
