The MAX7462/MAX7463 single-channel, standard-definition,
integrated video reconstruction filters and buffers
are ideal for anti-aliasing and digital-to-analog smoothing
video applications or wherever analog video is reconstructed
from digital data (such as cable/satellite/terrestrial
set-top boxes and DVRs).
The MAX7462 includes a disable function, which
places the output in a high-impedance state allowing
multiplexing of multiple output signals. It also has an
external gain control that sets the output buffer gain to
either +6dB or +9.5dB. The higher gain setting allows a
lower DAC output signal than the standard 1VP-P signal.
The MAX7463 output buffer has a fixed gain of
+6dB.
The MAX7462/MAX7463 operate from a single +5V
supply and have a flat passband out to 5MHz with a
stopband attenuation of -43dB (typ) at 27MHz.
These devices can drive two standard 150Ω AC-coupled
or DC-coupled video loads. The output black level
of the MAX7462/MAX7463 is less than 1V for DC-coupled
outputs.
The MAX7462 is available in an 8-pin µMAX® package
and an 8-pin SO package. The MAX7463 is available in
an 8-pin SO package. All devices are specified over
the 0°C to +85°C temperature range.
