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