Descriptions
The DIO2764 is a 4-Channel SDTV Video Amplifier
with 6th order filters and 6dB gain video filter.
These
four-channel
integrated
video
buffer
incorporates a 6th order Butterworth filter and able
to be bypassed.
The input can be configured for either ac or dc-
coupled inputs. The 300mV output level shift
allows for a full sync dynamic range at the output
with 0V input. The ac-coupled modes include a
transparent sync-tip clamp option for CVBS, Y',
and G'B'R' signals with sync. AC-coupled biasing
for C'/P'B/P'R channels can easily be achieved by
adding an external resistor.
The rail-to-rail output stage of DIO2764 with 6dB
gain allows for both ac and dc line driving. The
DIO2764 is an excellent choice for portable or
other power-sensitive applications.
