Noninverting TMDS, CML Input, Channel 2
Inverting TMDS, CML Input, Channel 2
Input Select, LVTTL Input. Force high to select input channel 1. Force low to select input channel 2.
Leave open to disable the output channel.
Preemphasis Select, LVTTL/LVCMOS Input. Force high for 6dB of output preemphasis. Leave open
for 3dB of output preemphasis. Force low for 0dB of output preemphasis (normal).
Hotplug Sense Input. Connect this pin to the display’s HOTPLUGx signal (buffered) to allow
automatic power-down of the associated output when the display is disconnected. A low-cost quad
5V, noninverting CMOS gate (74ACT32 series) is recommended to buffer the MAX3845 from the
HOTPLUGx pin to match HOTPLUG level specifications. If this feature is not used, connect to V
Supply Ground. Ground connection for input channel 2 and output channels 3 and 4.
