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 range of digital processors. The
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).
