Application Information FUNCTIONAL OVERVIEW The LMH6586 is a non-blocking analog video crosspoint switch with 32 input channels and 16 output channels. The inputs have integrated DC restore clamp circuits for biasing the AC-coupled video inputs. The fully buffered outputs have ...
Page 18
The switch can only be configured by programming through the I DC RESTORATION Because the LMH6586 uses a single 5V ...
Page 19
When shutdown the outputs are high impedance, which re- duces power consumption and crosstalk, and also enables multiple outputs to be connected together for expanding the matrix array size. Note that output short circuit protection is not provided, so care ...
