Notes
Optical parameters valid for each channel.
1. BER=10
12
at infinite ER. This means that the sensitivity specifica-
tion equals -13.7 dBm for an input signal with an ER of 5 dB.
2. P
FDA
: Average optical power when FRAME_DET switches from Low
to High.
P
FDD
: Average optical power when FRAME_DET switches from
High to Low.
Values are also applicable for SD11 function, except SD11 is low
active.
Figure 10. Timing diagrams
Strobe Mode
SCI Mode
In this operation mode the clock output is supplied in phase to data
outputs.
Note
1. All data outputs and clock output.
FRAME_DET and -RESET Timing Diagrams
Notes
1. Timing also applicable for SD11 function on fiber #12.
2. Stable frame input required. -RESET not activated.
3. Except when used as power-on reset. At any failure recovery,
-RESET should be brought to low level for at least t
3
.
4. Valid if -RESET is set high when V
CC
exceeds 3.0 V level and optical
FRAME (FRAME_DET=high) and data input are valid. t
5
starts when
all these conditions are fulfilled. -RESET must be set to Low during
power-up.
