Product Summary

The SAF7113H is a 9-bit video input processor. The SAF7113H 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; see Fig.1. The pure 3.3 V CMOS circuit SAF7113H, 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 ITU-R BT.601 compatible colour component values. The SAF7113H accepts as analog inputs CVBS or S-video (Y/C) from TV or VTR sources. The circuit is I2C-bus controlled.

Features

SAF7113H features: (1) Four analog inputs, internal analog source selectors, e.g. 4 ×CVBS or 2×Y/C or (1×Y/C and 2×CVBS); (2) Two analog preprocessing channels in differential CMOS style for best S/N-performance; (3) Fully programmable static gain or automatic gain control for the selected CVBS or Y/C channel; (4) Switchable white peak control; (5) Two built-in analog anti-aliasing filters; (6) 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; (7) On-chip clock generator; (8) Line-locked system clock frequencies; (9) Digital PLL for horizontal sync processing and clock generation, horizontal and vertical sync detection; (10) Requires only one crystal (24.576 MHz) for all standards; (11) Automatic detection of 50 and 60 Hz field frequency, and automatic switching between PAL and NTSC standards.
