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.
