The MAX9526 low-power video decoder converts NTSC or PAL composite video signals into 8-bit or 10-bit YCbCr component video, which complies with the ITU-R BT.656 standard. The device enters a full working mode and automatically configures when it is powered on, and decodes the detected input standard signal. The MAX9526 has a typical power consumption of 200mW in normal operation mode and less than 100µW in shutdown mode.
The internal 10-bit, 54MHz analog-to-digital converter (ADC) oversamples the input signal by 4 times. The MAX9526 has a DC recovery circuit with offset calibration and automatic gain control, which can accurately optimize the full-scale range of the ADC.
The integrated analog anti-aliasing filter eliminates external filtering components. The MAX9526 includes a 2: 1 input multiplexer, which automatically selects the signal based on the effective signal at the input.
The internal line-locked phase-locked loop (PLL) generates sampling clock and line-locked clock (LLC) outputs, providing ITU-compatible output. In addition, the PLL can be configured accordingly to provide a sampling clock and a clock that outputs 2 times and 1 times the crystal frequency, respectively.
The MAX9526 provides multiple adaptive comb filters to reduce chroma crosstalk and luma crosstalk.
Both the digital power supply and the analog power supply use a single 1.8V power supply. The digital output circuit is powered by an independent + 1.7V to + 3.45V power supply and can be directly connected to a digital processor with a wider voltage range. The MAX9526 operates over the -40 ° C to + 125 ° C automotive temperature range and is available in 28-pin QSOP and 32-pin TQFN (5mm x 6mm) packages.
