Power On Initialization Timings
Input Signal Definitions
Tx_DAT
A differential PECL serial data stream is presented to the GBIC for transmission onto the optical fiber by
intensity modulating a laser.
Tx_Disable
When high (logic one), the Tx_Disable signal turns
off the power to both the AC and DC laser driver cir-
cuits. It will also reset the Tx_Fault output under
some conditions (see Resetting a Fault (Tx_Fault)
on page 8).
When low (logic zero), the laser will be turned on
within 1ms if a hard fault is not detected. The timing
diagram below shows this line under normal operat-
ing conditions.
