t_OFF
TXDISABLE Assert Time
From input asserted to optical output
at 10% of nominal, C_COMP = 10nF.
t_ON
TXDISABLE De-assert Time
From input de-asserted to optical
output at 90% of nominal, C_COMP =
10nF.
t_INIT
Initialization Time
From power on or transmitter enabled
to optical output at 90% of nominal
and TX_FAULT de-asserted.⁽⁴⁾
t_INIT2
t_FAULT
Power-on Initialization Time
TXFAULT Assert Time
From power on to APC loop-enabled.
From fault condition to TXFAULT
assertion.⁽⁴⁾
t_RESET
Fault Reset Time
Length of time TXDISABLE must be
10
asserted to reset fault condition.
t_{LOSS_ON} RXLOS Assert Time
From loss of signal to RXLOS
asserted.
t_{LOSS_OFF} RXLOS De-assert Time
From signal acquisition to LOS de-
asserted.
t_DATA
Analog Parameter Data Ready
From power on to valid analog
parameter data available.⁽⁴⁾
t_{PROP_IN}
TXFAULT, TXDISABLE, RXLOS, Time from input change to
RSIN Input Propagation Time
