HSYNC
I/O
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
BLANK
Input section.
TTL Address Input. This signal sets up the LSB of the MPU address.
Teletext Data Request Output Signal, used to control teletext data transfer.
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.
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.
A 1200
resistor connected from this pin to GND is used to control full-scale amplitudes
of the Video Signals from DACs D, E, and F.
Compensation Pin for DACs D, E, and F. Connect a 0.1
μ
F Capacitor from COMP2 to V
AA
.
S-Video C/V/RED Analog Output. This DAC is capable of providing 4.33 mA output.
S-Video Y/U/BLUE Analog Output. This DAC is capable of providing 4.33 mA output.
Composite/Y/GREEN Analog Output. This DAC is capable of providing 4.33 mA output.
S-Video C/V/RED Analog Output. This DAC is capable of providing 4.33 mA output.
S-Video Y/U/BLUE Analog Output. This DAC is capable of providing 4.33 mA output.
Composite/Y/GREEN Analog Output. This DAC is capable of providing 4.33 mA output.
Compensation Pin for DACs A, B, and C. Connect a 0.1
μ
F Capacitor from COMP1 to V
AA
.
Voltage Reference Input for DACs or Voltage Reference Output (1.235 V). An external
V
REF
cannot be used in 4
×
oversampling mode.
A 1200
resistor connected from this pin to GND is used to control full-scale amplitudes
of the Video Signals from DACs A, B, and C.
The input resets the on-chip timing generator and sets the ADV7190/ADV7191 into default
mode. See Appendix 8 for Default Register settings.
Dual function
CSO
or
HSO
Output Sync Signal at TTL Level.
Multifunction Pin.
VSO
Output Sync Signal at TTL level. CLAMP TTL Output Signals
can be used to drive external circuitry to enable clamping of all Video Signals.
Input signal to select PAL or NTSC mode of operation, pin set to Logic 1 selects PAL.
No Connect.
Teletext Data Input Pin.
