Condition
From input asserted to optical output
at 10% of nominal, C
From input de-asserted to optical
output at 90% of nominal, C
10nF.
From power on or transmitter enabled
to optical output at 90% of nominal
and TX_FAULT de-asserted.
From power on to APC loop-enabled.
From fault condition to TXFAULT
assertion.
Length of time TXDISABLE must be
asserted to reset fault condition.
From loss of signal to RXLOS
asserted.
From signal acquisition to LOS de-
asserted.
From power on to valid analog
parameter data available.
Time from input change to
corresponding internal register bit set
or cleared.
From an internal register bit set or
cleared to corresponding output
change.
Note 4
Maximum length pulse that will not
cause output to change state.
