Pin Description
Inverting and non-inverting high speed LVDS input pins.
Inverting and non-inverting high speed LVDS output pins.
Receive equalization level select pins.
Transmit pre-emphasis level select pins.
Channel output power down pins. When the PWDNn is set to L,
the channel output OUTn is in the power down mode. The LOS
circuitry on the corresponding input remains enabled.
Loss Of Signal output pins, LOSn report when an open input fault
condition is detected at the input, INn. These are open drain
outputs. External pull up resistors are required.
NO CONNECT pins. May be left floating.
Device power down pin. When the PWDN is set to L, the device
is in the power down mode. The LOS circuitry is disabled as well.
Power supply pins.
Ground pin and a pad (DAP - die attach pad).
