Technical Data

NOTE:
The Sync Processor is designed to detect and process sync signals
inside a digital monitor system — from separated Hsync and Vsync
inputs. After detection and the necessary polarity correction and/or sync
separation, the corrected sync signals are sent out. The MCU can also
send commands to other monitor circuitry, such as for the geometry
correction and OSD, using the DDC12AB and/or the IIC communication
channels.

All quoted timings in this section assume an internal bus frequency of
6MHz.

Polarity detector
Horizontal frequency counter
Vertical frequency counter
Low vertical frequency indicator (40.7Hz)
Polarity controlled HOUT and VOUT outputs:
– From separate Hsync and Vsync
– From composite sync on HSYNC input pin
– From internal selectable free running Hsync and Vsync pulses
Free-running Hsync, Vsync, DE, and DCLK of 4 video modes
CLAMP pulse output to the external pre-amp chip
Internal schmitt trigger on HSYNC, and VSYNC input pins to
improve noise immunity
