DESCRIPTION

· The PI7VD9008H is an 8-channel video decoder and audio codec designed for security applications, supporting D1 and 960H video resolutions with a single 27MHz reference crystal clock frequency.

· It features a 10-bit ADC per audio channel, proprietary clamp, automatic gain controller, and a 5H comb filter for noise reduction.

· The device includes a resilient sync-tip detection algorithm for noisy environments and a built-in audio digital controller for I2S outputs.

FEATURES

· High-quality live 8-channel video/audio decoder supporting WD1(960H) and D1(720H) cameras.

· Proprietary video decoder optimized for weak, noisy, or unstable signal recovery.

· Resilient sync-tip detection for locking video signals in noisy environments.

· Programmable luminance peaking for enhanced sharpness, hue, saturation, and contrast.

· Flexible ITU-R BT.656 video output with multiple frequency options.

· Supports NTSC and PAL formats with a single 27.0 MHz reference clock.

· 8-channel composite video or 4-channel S-video inputs.

· Fully differential CMOS analog pre-processing channel with clamping and AGC.

· Complementary 5H adaptive comb filters for noise reduction.

· Built-in audio codec with ten analog audio inputs and one audio output.

· Supports I2S and DSP serial audio formats.

· Integrated video PLL for 108MHz clock output and low power consumption.

· Two-wire serial interface (I2C) for control of brightness, contrast, saturation, hue, and sharpness.

APPLICATIONS
