【简　介】:
The AL128EVB is an engineering evaluation board that is used to evaluate and demonstrate the
performance of the AL128 VGA-to-TV scan converter chip. The board contains an AL128,
512Kbytes of field memory (two 256KB chips), an AV9173 video clock generator (PLL), and
either one or two crystal oscillators. An attached microcontroller daughter board is used to
demonstrate the AL128’s I2C programmability and its capability of supporting full 1024x768
resolution, and will be introduced in the Supplement Pages.
