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 Verti-
cal 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. Alterna-
tively, 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.
Compensation Pin for DACs D, E, and F. Connect a 0.1

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 ADV7194 into default mode
See Appendix 8 for Default Register settings.
Dual function
CSO
or
HSO
output Sync Signal at TTL level.
Multifunctional Pin.
VSO
Output Sync Signal at TTL level. Teletext Data Input pin.
CLAMP TTL Output Signals can be used to drive external circuitry to enable clamping
of all Video Signals.
