Low-Power, High-Performance
NTSC/PAL Video Decoder
General Description
The MAX9526 is a low-power video decoder that con-
verts NTSC or PAL composite video signals to 8-bit or
10-bit YCbCr component video compliant with the ITU-
R BT.656 standard. The device powers up in fully oper-
ational mode and automatically configures itself to
decode the detected input standard. The MAX9526
typically consumes 200mW of power in normal opera-
tion and typically less than 100µW in shutdown mode.
An internal 10-bit, 54MHz analog-to-digital converter
(ADC) samples the input with four times oversampling.
The MAX9526 features a DC restoration circuit with off-
set correction and automatic gain control to accurately
optimize the full-scale range of the ADC.
An integrated analog anti-aliasing filter eliminates the
need for external filtering. The MAX9526 includes a 2:1
input multiplexer with automatic signal selection based
on activity at the inputs.
An internal line-locked phase-locked loop (PLL) gener-
ates the sample clock and the line-locked clock (LLC)
output to provide an ITU-compliant output. Alternatively,
the PLL can be configured to provide a sample clock
and output clock at 2x and 1x the frequency of the
crystal oscillator, respectively.
The MAX9526 provides a multiline adaptive comb filter to
reduce cross-chrominance and cross-luminance artifacts.
A single 1.8V supply is used for both the digital and
analog supplies. The digital outputs operate from a
separate +1.7V to +3.45V supply to allow direct con-
nection to a wide ranFguenocf tdiigointaal plrDocieasgsorras.mThse
MAX9526 operates over the -40°C to +125°C automo-
tive temperature range and is available in both a
28-pin QSOP and a 32-pin TQFN (5mm x 6mm).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
