HSYNC
(Modes 1, 2, and 3) Control Signal. This pin may be configured to be an output
(Master Mode) or an input (Slave Mode) and accept Sync Signals.
VSYNC
Control Signal. This pin may be configured as an output (Master Mode) or as an
input (Slave Mode) and accept
VSYNC
as a Control Signal.
Video Blanking Control Signal. This signal is optional. For further information see
Vertical Blanking and Data Insertion Blanking Input section.

10-Bit Progressive Scan Input Port for Cb data.
Teletext Data Request Output Signal, used to control teletext data transfer.
Analog Ground.
TTL Clock Input. Requires a stable 27 MHz reference clock for standard operation.
Alternatively, a 24.5454 MHz (NTSC) or 29.5 MHz (PAL) can be used for square pixel
operation.
Clock Output pin.
Analog Power Supply (3.3 V to 5 V).
MPU Port Serial Interface Clock Input.
MPU Port Serial Data Input/Output.
Multifunctional Input: Real Time Control (RTC) input, Timing Reset input, Subcarrier
Reset input.
TTL Address Input. This signal sets up the LSB of the MPU address.
A 1200
resistor connected from this pin to GND is used to control full-scale amplitudes
of the Video Signals from the DAC D, E, F.

Oversampling Mode.
A 1200
resistor connected from this pin to GND is used to control full-scale amplitudes
of the Video Signals from the DAC A, B, C.
Input signal to select PAL or NTSC mode of operation, pin set to Logic 1 selects PAL.
The input resets the on-chip timing generator and sets the ADV7192 into default mode.
See Appendix 8 for Default Register settings.
