Ground. The ground return for all circuitry on-chip. It is recommended that the
ADV7511 be assembled on a single, solid ground plane with careful attention
given to ground current paths.
C Serial Port Data I/O. This pin serves as the serial port data I/O slave for register
access. Supports CMOS logic levels from 1.8V to 3.3V.
C Serial Port Data Clock input. This pin serves as the serial port data clock slave for
register access. Supports CMOS logic levels from 1.8V to 3.3V.
C Serial Port Data I/O to Sink. This pin serves as the master to the DDC bus. Tolerant
of 5 V CMOS logic levels.
C Serial Port Data Clock to Sink. This pin serves as the master clock for the DDC
bus. Tolerant of 5 V CMOS logic levels.
I CEC clock. From 1MHz to 100Mhz. Supports CMOS logic levels from 1.8V to 5V.
I/O CEC data signal. Supports CMOS logic levels from 1.8V to 5V.
