Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

Description
The FMS6501A switch matrix provides flexible options
for today’s video applications. The device has twelve
(12) inputs that can be routed to any of the nine (9)
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 controlled via an
2
I C-compatible digital interface.
Each input supports an integrated clamp option to set
the output sync-tip level of video with sync to
approximately 300 mV. Alternatively, the input may be
internally biased to center signals without sync
(Chroma, Pb, Pr) at approximately 1.25 V. These DC
output levels are for the 6 dB gain setting. Higher gain
settings increase the DC output levels accordingly. The
2
input clamp/bias mode is selected via I C control.
Unused outputs may be powered down to reduce power
