Description
AH4
pgtx1
TP
PVT compensation circuit overdrive voltage for client
side LVDS drivers; for test only. This pin should be left
floating for functional operation at 10-G rates. For
non-10-G applications, this pin should be brought out
to a resistor divider network. An external voltage is
required to be applied at this pin in the range of 1.2 V
to 1.4 V for normal operation.
G31
pgtx0
TP
PVT compensation circuit overdrive voltage for line
side LVDS drivers; for test only. This pin should be left
floating for functional operation at 10-G rates. For
non-10-G applications, this pin should be brought out
to a resistor divider network. An external voltage is
required to be applied at this pin in the range of 1.2 V
to 1.4 V for normal operation.
