Description
The FMS6501 provides 12 inputs which can be routed to any of
9 outputs. Each input can be routed to one or more outputs but
only one input may be routed to any output. The input to output
routing is controlled 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. Alternatively, the
input may be internally biased to center signals without sync
(Chroma, Pb, Pr) at ~1.25V. These DC output levels are for the
6dB gain setting. Higher gain settings will increase the DC out-
put levels accordingly. The input clamp / bias mode is selected
via I²C.
Unused outputs may be powered down to reduce power dissi-
pation.
