DESCRIPTION
Connected to a host MCU via a serial I²C Bus, the
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.
