Unit Notes
µs
Time from rising edge of TX_DIS
to when the optical output falls
below 10% of nominal.
ms Time from falling edge of TX_DIS
to when the modulated optical
output rises above 90% of nominal.
ms From power on or hot plug after
meeting power supply specs
ms From occurrence of the condition
triggering interrupt
us
From clear on read interrupt flags
us
From Power down initiation
ms Max delay from negate to comple-
tion of power up and reset
ms From Occurrence of fault to asser-
tion of Mod_NR
ms From Occurrence of signal to nega-
tion of Mod_NR
ms Maximum delay between assertion
of Mod_DeSel and end of module
response to 2-wire interface com-
munications
ms Maximum delay between de-as-
sertion of Mod_DeSel and proper
module response to 2-wire inter-
facecommunications
µs
Min length of P-Down assert to
initial reset
µs
From Occurrence of loss of signal
to assertion of RX_LOS
µs
From Occurrence of presence of
signal to negation of RX_LOS
