MAX9526ATJ+ General Description

The MAX9526 is a low-power video decoder that con-verts NTSC or PAL composite video signals to 8-bit or10-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 todecode the detected input standard. The MAX9526typically 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 accuratelyoptimize the full-scale range of the ADC.An integrated analog anti-aliasing filter eliminates theneed for external filtering. The MAX9526 includes a 2:1input multiplexer with automatic signal selection basedon 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 clockand output clock at 2x and 1x the frequency of thecrystal oscillator, respectively.The MAX9526 provides a multiline adaptive comb filter toreduce cross-chrominance and cross-luminance artifacts.A single 1.8V supply is used for both the digital andanalog supplies. The digital outputs operate from aseparate +1.7V to +3.45V supply to allow direct con-nection to a wide range of digital processors. TheMAX9526 operates over the -40°C to +125°C automo-tive temperature range and is available in both a28-pin QSOP and a 32-pin TQFN (5mm x 6mm).
