GBIC timing parameters for GBIC management

Parameter	Symbol	Min.	Max.	Unit	Unit Conditions
TX_DISABLE assert time	t_off		10	μsec	Rising edge of TX_DISABLE to fall of output signal
					below 10% of nominal
TX_DISABLE negate	t_on		1	mec	Falling edge of TX_DISABLE to rise of output
time					signal above 90% of nominal
Time to initialize,					From power on or hot plug fter V DD T > 4.75 volts
includes reset of	t_init		300	msec	or From negation of TX_DISABLE during reset of
TX_FAULT					TX_FAULT.
TX_FAULT from fault to	t_fault		100	μsec	From occurrence of fault (out-put safety violation or
assertion					V DD T < 4.5 volts)
TX_DISABLE time to	t_rest	10		μsec	TX_DISABLE HIGH before TX_DISABLE set LOW
start reset
RX_LOS assert delay	t_loss_on		100	μsec	From detection of loss of signal to assertion of
					RX_LOS
RX_LOS negate delay	t_loss_off		100	μsec	From detection of presence of signal to negation of
					RX_LOS
