GENERAL DESCRIPTION
The one chip front-end SAA7110; SAA7110A is a digital multistandard colour decoder (OCF1) on the basis of the DIG-TV2 system with two integrated Analog-to-Digital Converters (ADCs), a Clock Generation Circuit (CGC) and Brightness Contrast Saturation (BCS) control.

FEATURES
• Six analog inputs (6 × CVBS or 3 × Y/C or combinations)
• Three analog processing channels
• Three built-in analog anti-aliasing filters
• Analog signal adding of two channels
• Two 8-bit video CMOS analog-to-digital converters
• Fully programmable static gain for the main channels or automatic gain control for the selected CVBS/Y channel
• Selectable white peak control signal
• Luminance and chrominance signal processing for PAL B/G, NTSC M and SECAM
• Full range HUE control
• Automatic detection of 50/60 Hz field frequency, and automatic switching between standards PAL and NTSC, SECAM forceable
• Horizontal and vertical sync detection for all standards
• Cross-colour reduction by chrominance comb filtering for NTSC or special cross-colour cancellation for SECAM
• UV signal delay lines for PAL to correct chrominance phase errors
• The YUV-bus supports a data rate of: – 780 × fh = 12.2727 MHz for 60 Hz (NTSC) – 944 × fh = 14.75 MHz for 50 Hz (PAL/SECAM)
• Square pixel format with 768/640 active samples per line on the YUV-bus
• CCIR 601 level compatible
• 4 : 2 : 2 and 4 : 1 : 1 YUV output formats in 8-bit resolution
• User programmable luminance peaking for aperture correction
• Compatible with memory-based features (line-locked clock, square pixel)
• Requires only one crystal (26.8 MHz) for all standards
• Real time status information output (RTCO)
• Brightness Contrast Saturation (BCS) control for the YUV-bus
• Negation of picture possible
• One user programmable general purpose switch on an output pin
• Switchable between on-chip Clock Generation Circuit (CGC) and external CGC (SAA7197)
• Power-on control
• I2C-bus controlled.
