GENERAL DESCRIPTION
The memory controller SAA4951 has been designed for high end TV sets using 2fH-technics. The circuit provides all necessary write, read and clock pulses to control different field memory concepts. Furthermore the drive signals for the horizontal and vertical deflection power stages are generated.

FEATURES
• Support for acquisition, display and deflection PLL
• 50/100 (or 60/120) Hz scan conversion for different input data rates: 12, 13.5, 16 and 18 MHz
• Support for 4:3 and 14:9 display on a 16:9 screen (horizontal compression)
• Support for Y:U:V data rates of 4:1:1, 4:2:2, and 4:4:4
• Horizontal zoom
• Still picture
• Support for one or two field memories
• Support for different video memory types like TMS 1050/60/70/2970
• Progressive scan
• Programmable via microcontroller port
• Golden Scart option
• Support for Multi-PIP.
