Delta Electronics LCP-155B4MSRx SFP timing parameters for SFP management, Txdisable, Txfault

SFP timing parameters for SFP management

Parameter	Symbol	Min.	Max.	Unit	Unit Conditions
TX_DISABLE Assert	t_off		10		Time from rising edge of TX_DISABLE to
				µsec	when the optical output falls below 10% of
time
					nominal
TX_DISABLE	t_on		1	msec	Time from falling edge of TX_DISABLE to
					when the modulated optical output rises
Negate time
					above 90% of nominal
Time to initialize,	t_init		300	msec	From power on or negation of TX_Fault using
including reset of
TX_FAULT					TX Disable.
TX Fault Assert	t_fault		100	µsec	Time from fault to TX fault on.
Time
TX_DISABLE to	t_rest	10		µsec	Time TX Disable must be held high to reset
reset					TX_Fault
LOS Assert Time	t_loss_on		100	µsec	Time from LOS state to Rx LOS assert
LOS Deassert Time	t_loss_off		100	µsec	Time from non-LOS state to Rx LOS deassert
Serial ID Clock Rate	f_serial_clock		100	kHz
