Pin Description
Inverting and non-inverting high speed LVDS input pins.
Inverting and non-inverting high speed LVDS output pins.
This pin selects which LVDS input is active.
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.
Channel output power down pin. When the PWDNn is set to L, the
channel output OUTn is in the power down mode.
Device power down pin. When the PWDN is set to L, the device
is in the power down mode.
Power supply pins.
Ground pin and a pad (DAP - die attach pad).
NO CONNECT pins. May be left floating.
