Delta Electronics LCP-200A4HSR manual 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,																	From power on or negation of TX_Fault using
	including reset of								t_init				300		msec
	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 Disbale 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
