Exc eeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside of its operating rating.
Device is ESD sensitive. Use appropriate ESD precautions. Exceeding the absolute maximum rating may damage the device.
Sensitivity is defined as the average signal level measured at the input necessary to achieve 10 -2 BER (bit error rate). The input signal is defined
as a return-to-zero (RZ) waveform with 50% average duty cycle (Manchester encoded) at a data rate of 1kbps.
When data burst does not contain preamble, duty cycle is defined as total duty cycle, including any “quiet” time between data bursts. When data
bursts contain preamble sufficient to charge the slice level on capacitor C TH , then duty cycle is the effective duty cycle of the burst alone. [For
example, 100msec burst with 50% duty cycle, and 100msec “quiet” time between bursts. If burst includes preamble, duty cycle is
T ON /(T ON +t OFF )= 50%; without preamble, duty cycle is T ON /(T ON + T OFF + T QUIET ) = 50msec/(200msec)=25%. T ON is the (Average number of
1’s/burst) × bit time, and T OFF = (T BURST – T ON .)
