STV9432 Datasheet PDF - STMicroelectronics

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 character sizes and colors. A built-in digital PLL, operating at very high frequency, provides an accurate display without visible jitter for a wide line frequency range from 15 to 140 kHz.
