Description
The FMS6501 switch matrix provides flexible options for
today’s video applications. The 12 inputs that can be
routed to any of nine outputs. Each input can be routed
to one or more outputs, but only one input may be routed
to any one output. The input to output routing is con-
trolled via an I²C™-compatible digital interface.
Each input supports an integrated clamp option to set the
output sync tip level of video with sync to ~300mV. Alter-
natively, the input may be internally biased to center sig-
nals without sync (Chroma, Pb, Pr) at ~1.25V. These DC
output levels are for the 6dB gain setting. Higher gain
settings increase the DC output levels accordingly. The
input clamp / bias mode is selected via I²C.
Unused outputs may be powered down to reduce power
dissipation.
