DESCRIPTION

STV9432TA is a multifunction slave peripheral

device integrating the ON-Screen-Display block.

The On-screen Display (OSD) includes a MASK

PROGRAMMABLE ROM that holds the CUSTOM

CHARACTER FONT, a 1Kbytes RAM that stores

the code strings of the different lines of text to be

displayed, and a set of registers to program char-

acter sizes and colors. A built-in digital PLL, oper-

ating at very high frequency, provides an accurate

display without visible jitter for a wide line fre-

quency range from 15 to 140 kHz.
