BER Meas End A signal at this pin indicates the status of the bit error
rate (BER) measurements. BER measurements are
being executed when the signal is high.
BER Sync loss A low signal at this pin indicates that the
synchronization is lost. This signal is valid only when the
signal at the BER Meas End pin is high.
BER Test Out A signal at this pin indicates the test result of the bit
error rate measurements. The result is guaranteed at
the falling edge of the BER Meas End signal. The result
is pass when the signal is low; the result is fail when the
signal is high. The signal is also high when the pass/fail
judgment is set to off.
BER Error Out A signal at this pin indicates the number of the error
bits. The output is normally low. One pulse signal (pulse
width matches the input clock) indicates one error bit.
Pulses for the error bits of one measurement cycle are
