Figure 7 - DATA and DCLK Output Timing
dBm=decibels above or below a reference power of 1mW into 600 .
Using unity gain test circuit shown in Figure 6.
Mark and Space frequencies have the same amplitude.
Band limited random noise (200-3200Hz).
Referenced to the minimum input detection level.
FSK input data at 1200 ±12 baud.
OSC1 at 3.579545 MHz ±0.2%.

Function of signal condition.
The device will stop functioning within this time, but more time may be required to reach I
For a repeating mark space sequence, the data stream will typically have equal 1 and 0 bit durations.
