Hot-selling and scarce SAA7113H/V2 9-bit video input processor QFP spot stock

Product Descriptions

The 9-bit video input processor is a combination of a two-channel analog preprocessing circuit including source selection, anti-aliasing filter and ADC, an automatic clamp and gain control, a Clock Generation Circuit (CGC), a digital multi-standard decoder (PAL BGHI, PAL M, PAL N, combination PAL N, NTSC M, NTSC-Japan, NTSC N and SECAM), a brightness, contrast and saturation control circuit, a multi-standard VBI data slicer and a 27 MHz VBI data bypass.

The pure 3.3 V (5 V compatible) CMOS circuit SAA7113H, analog front-end and digital video decoder, is a highly integrated circuit for desktop video applications. The decoder is based on the principle of line-locked clock decoding and is able to decode the colour of PAL, SECAM and NTSC signals into CCIR-601 compatible colour component values. The SAA7113H accepts as analog inputs CVBS or S-video (Y/C) from TV or VTR sources. The circuit is I2C-bus controlled.​

Product Features

• Four analog inputs, internal analog source selectors, e.g. 4 × CVBS or 2 × Y/C or (1 × Y/C and 2 × CVBS)

• Two analog preprocessing channels in differential CMOS style for best S/N-performance

• Fully programmable static gain or automatic gain control for the selected CVBS or Y/C channel

• Switchable white peak control

• Two built-in analog anti-aliasing filters

• Two 9-bit video CMOS Analog-to-Digital Converters (ADCs), digitized CVBS or Y/C-signals are available on the VPO-port via I2C-bus control

• On-chip clock generator

• Line-locked system clock frequencies

• Digital PLL for horizontal sync processing and clock generation, horizontal and vertical sync detection

• Requires only one crystal (24.576 MHz) for all standards

• Automatic detection of 50 and 60 Hz field frequency, and automatic switching between PAL and NTSC standards

• Luminance and chrominance signal processing for PAL BGHI, PAL N, combination PAL N, PAL M, NTSC M, NTSC N, NTSC 4.43, NTSC-Japan and

SECAM

• User programmable luminance peaking or aperture correction

• Cross-colour reduction for NTSC by chrominance comb filtering
