Detailed Description
The MAX7428/MAX7430/MAX7432 filter and buffer the
outputs of DAC encoder chipsets that process digital
video information in applications such as set-top boxes,
hard-disk recorders, DVD players, recorders, and digi-
tal VCRs. These devices also filter and
“
clean-up
”
ana-
log video signals. Each channel in the MAX7428/
MAX7430/MAX7432 includes an input mux to select the
input channel, a 6th-order Sallen-Key filter with four
adjustable high-frequency boost levels, an output
buffer with a 6dB gain, a sync detector and clamp, and
an external resistor to set internal bias levels. Output
disable adds additional multiplexing in a wired-OR con-
figuration. Filter bypass, in conjunction with the two
inputs, can be used to provide filtered and unfiltered
video signal processing. Maxim
’
s Single Pin Bus
(MSPB) interface controls all of the above features. An
external capacitor is used to assign each device a
unique address that allows control of up to 16 devices
on the same bus. Typical application circuits for the
MAX7428/MAX7430/MAX7432 are shown in Figures 1,
2, and 3.
Input Considerations
Use a 0.1μF ceramic capacitor to AC-couple the input
to the MAX7428/MAX7430/MAX7432. This input capaci-
tor stores a DC level to level-shift the input signal to an
optimal point between V
CC
and GND. The ABSEL bit on
the Control Register sets which channel (IN_A or IN_B)
is selected (
Control Register
section). The IN_A and
IN_B inputs have a typical input resistance of 50k
.
