Output Signal Timings

JGB-10SYAA1
Fibre Channel GBIC
Rx_DAT
The incoming optical signal is converted and repowered as an AC coupled differential PECL serial data
stream.
Rx_LOS
The Receive Loss of Signal line is high (a logical one) when there is no incoming light from the companion
transceiver. (More accurately, this line indicates that the level of light is below that required to guarantee cor-
rect operation of the link. Normally, this only occurs when either the link is unplugged or the companion trans-
ceiver is turned off.) This signal is normally used by the system for diagnostic purposes. The timing is shown
in the Receive Loss of Signal Detection diagram below.
This signal has an open collector TTL driver. A pull up resistor is required on the host side of the GBIC con-
nector. The recommended value for this resistor is 10 k .
Tx_Fault
Upon sensing an improper power level in the laser driver, the GBIC sets this signal high and turns off the
laser. The Tx_Fault signal can be reset with the Tx_Disable line.
The laser is turned off within 100 s as shown in the Transmitter Fault Detection timing diagram below.
This signal has an open collector TTL driver. A pull up resistor is required on the host side of the GBIC con-
nector. The recommended value for this resistor is 10 k .
