Pulse Count Detection
A LOS alarm is detected if the incoming data stream has no
transitions for a programmable number T consecutive pulse
positions. The number T is programmable via the PCD register and
can be calculated as follows:
T= 16
The maximum time is: 256 x 16 x 488 ns = 2 ms. Every detected pulse
resets the internal pulse counter. The counter is clocked with the
receive clock RCLK.
Pulse Count Recovery
A LOS alarm is cleared if a pulse density is detected in the received
bit stream. The number of pulses M which must occur in the
predefined PCD time interval is programmable via the PCR register
and can be calculated as follows:
M = N+1 ; with 0
The time interval starts with the first detected pulse transition. With
every received pulse a counter is incremented and the actual counter
is compared with the contents of PCR register. If the pulse number is
active. In this case the next detected pulse transition starts a new time
interval.
