General Description
The MAX7448, 4-channel, buffered video reconstruc-
tion filter is ideal for anti-aliasing and digital-to-analog
converter (DAC)-smoothing video applications or wher-
ever analog video is reconstructed from a digital data
stream (such as cable/satellite/terrestrial set-top boxes,
DVD players, hard-disk recorders (HDRs), and person-
al video recorders (PVRs)). This device operates from a
single +5V supply and has a flat passband out to 5MHz
with a stopband attenuation of 43dB at 27MHz. This
makes it ideal for use with NTSC, PAL, and standard-
definition digital TV (SDTV) video systems. Each output
is capable of driving two standard 150
video loads.
The MAX7448 processes RGB and asynchronous CVBS
video signals. The output video buffers have a fixed gain
of +6dB. The channel used for CVBS video has high-fre-
quency boost circuitry, which provides picture sharpness
with +1.2dB of gain boost without degradation in the
stopband. The output video drivers can be disabled with
an external pin.
The MAX7448 is available in a 14-pin TSSOP package
with an exposed pad, and is specified over the -40°C to
+85°C extended temperature range.
