E510+-1
This product uses the internal function of Mascot V (U1) as a signal detector in order to
support separate SYNC, composite SYNC and SYNC on GREEN signals. The analog input
Horizontal and Vertical Sync signals pass through the Schmitt trigger buffer U4 to stabilize
then input to Mascot U1 pin38 VGA_VSYNC, pin39 VGA_HSYNC or pin40 SOGI and the
image processing. Then Mascot will detect the signal type if it is separate SYNC, composite
SYNC or SOG. MPU (U6) reads the input signal type from IIC protocol and does the correct
procedure to generate the proper signals to the whole system.
24LC02 (U14) chip provide DDC1/2B
¥
with Analog Plug & Play, and the DDC data format is
EDID v1.3.
