SAA4951 - Memory controller

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.

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.
