MAX9652/MAX9653/MAX9654
Detailed Description
The MAX9652/MAX9653/MAX9654 are HD video-filter
amplifiers that operate from a 3.3V supply. They can be
used to lowpass filter the signal after a video digital-to-
analog converter (DAC) or before a video analog-to-
digital converter (ADC). The inputs to the parts must be
AC-coupled; the outputs can be AC- or DC-coupled.
The average power consumption of the parts is signifi-
cantly less than the average power consumption of the
5V generation of HD video filter amplifiers. The quies-
cent power consumption of the MAX9654 is 95mW, and
the average power consumption, which is defined when
the parts drive a 150
Ω load to ground with color bars, is
200mW.
The MAX9652 is the simplest member of the family, with
neither selectable SD/HD filters nor shutdown capabili-
ty. This device is best suited for line-powered equip-
ment such as set-top boxes, DVD players, and A/V
receivers.
The MAX9653 has shutdown capability and is a natural
fit in portable equipment and line-powered equipment
in which standby power consumption is a concern. The
MAX9653 is also an option in SCART set-top boxes with
analog high-definition video outputs. In those designs,
the same triple DAC typically generates both the stan-
dard-definition RGB signals that are routed through the
SCART device (refer to the MAX9598 data sheet) and
the high-definition YPbPr signals that are routed
through the MAX9653. Only one signal set is output at
any given time, and so the device connected to the
unused outputs must be shut down.
The MAX9654 has both selectable SD/HD filters and
shutdown capability. The applications of the MAX9654
are similar to those of the MAX9653, but the MAX9654
provides the additional capability to switch between
standard-definition and high-definition formats. The
MAX9654 has a passband (±1dB) of 42MHz for high-
definition signals and a passband of 8.5MHz for stan-
dard-definition signals.
Inputs
Video signals must be AC-coupled into the MAX9652/
MAX9653/MAX9654 using 0.1F capacitors. An input
sync tip clamp sets the DC level for the luma signal at
YIN. Keyed clamps on PBIN and PRIN set the DC bias
of the color difference signals at PBIN and PRIN. When
the input sync tip clamp detects a sync pulse on the
luma signal, it generates a signal that activates the
keyed clamps on PBIN and PRIN.
In shutdown mode, the inputs to the MAX9653 and the
MAX9654 do not distort the video signal in case the
outputs of the video DAC are also connected to another
video circuit such as a dual SCART device. See the
SCART Set-Top Box with Analog HD Outputs section.
The inputs in shutdown mode are biased at VDD/3,
which is sufficiently above ground so that the ESD
diodes never forward bias as the video signal changes.
The input resistance in shutdown is 220k
Ω which pre-
sents negligible loading on the video current DAC.
HD Video Filter
The MAX9652/MAX9653/MAX9654 have a six-pole,
Butterworth filter with a typical passband (±1dB) of
