DC Characteristics
Table 5: LVDS and TTL Inputs and Outputs
Hot Swap
The LVDS input and output buffers are subject to hot swap events while being connected and disconnected from
the passive backplane. If the input is powered down but still receiving a signal from an output, the input must tolerate
extra input current and power. If the input is powered up but has no input connection, it must go to a valid logic state.
The Table 6 below lists the LVDS I/O parameters that relate to hot swap condition.
