MAX9526 - Maxim Integrated Products

MAX9526 High-Performance NTSC/PAL Video Decoder

The MAX9526 is a low-power video decoder that converts NTSC or PAL composite video signals to 8-bit or 10-bit YCbCr component video compliant with the ITUR BT.656 standard. The device powers up in fully operational mode and automatically configures itself to decode the detected input standard. The MAX9526 typically consumes 200mW of power in normal operation.

Features

a DC restoration circuit with offset 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) generates 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 cryst.
