13 DTV / NIC Decision Threshold Voltage 3)
1) : Package is at same potential as GND .
2) : LPA output is a logic level that indicates the presence or absence of a sufficient optical input level.
A logical high level indicates an input optical level is too low.
3) : DTV (0.5 to 3.5V). This pin is left open if the amplitude decision threshold is not made adjustable.
