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).
