Description
The FMS6502 provides eight inputs that can be routed to
any of six outputs. Each input can be routed to one or
more outputs, but only one input may be routed to any
output.
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 out-
put signals without sync (Chroma, Pb, Pr) at ~1.25V.
All outputs are designed to drive a 150Ω DC-coupled
load. Each output can be programmed to provide either
0dB or 6dB of signal gain.
Input-to-output routing and input bias mode functions are
controlled via an I²C-compatible digital interface.
Applications
■ Cable and Satellite Set-Top Boxes
■ TV and HDTV Sets
■ A / V Switchers
■ Personal Video Recorders (PVR)
■ Security and Surveillance
■ Video Distribution
■ Automotive (In-Cabin Entertainment)
