I/O
I 8-Bit or 16-Bit 4:2:2 Multiplexed YCrCb Pixel Port. The LSB of the input data is set up on Pin P0.
P Analog Power Supply (3.3V to 5V).
G Analog Ground.
HSYNC (Modes 1, 2, and 3) Control Signal. This pin may be configured to be an output
I/O
(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
I/O
(Slave Mode) and accept VSYNC as a Control Signal.
Video Blanking Control Signal. This signal is optional. For further information see Vertical
I/O
Blanking Data Insertion and BLANK Input section.
I TTL Address Input. This signal sets up the LSB of the MPU address.
O Teletext Data Request Output Signal, used to control teletext data transfer.
TTL Clock Input. Requires a stable 27 MHz reference clock for standard operation. Alternatively,
I
a 24.5454 MHz (NTSC) or 29.5 MHz (PAL) can be used for square pixel operation.
O Clock Output Pin.
I MPU Port Serial Interface Clock Input.
I/O MPU Port Serial Data Input/Output.
Multifunctional Input: Real-Time Control (RTC) Input, Timing Reset Input,
I
Subcarrier Reset Input.
A 1200 ohm resistor connected from this pin to ground is used to control full-scale amplitudes of
I
the Video Signals from DACs D, E, and F.
O Compensation Pin for DACs D, E, and F. Connect a 0.1µF Capacitor from COMP2 to VAA.
O S-Video C/V/RED Analog Output. This DAC is capable of providing 4.33 mA output.
O S-Video Y/U/BLUE Analog Output. This DAC is capable of providing 4.33 mA output.
O Composite/Y/GREEN Analog Output. This DAC is capable of providing 4.33 mA output.
O S-Video C/V/RED Analog Output. This DAC is capable of providing 4.33 mA output.
O S-Video Y/U/BLUE Analog Output. This DAC is capable of providing 4.33 mA output.
O Composite/Y/GREEN Analog Output. This DAC is capable of providing 4.33 mA output.
O Compensation Pin for DACs A, B, and C. Connect a 0.1µF Capacitor from COMP1 to V
Voltage Reference Input for DACs or Voltage Reference Output (1.235V). An external V
I/O
cannot be used in 4x oversampling mode.
A 1200 ohm resistor connected from this pin to ground is used to control full-scale amplitudes of
I
the Video Signals from DACs A, B, and C.
The input resets the on-chip timing generator and sets the ADV7190/ADV7191 into default
I
mode. See Appendix 8 for Default Register Settings.
O 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
I/O
used to drive external circuitry to enable clamping of all Video Signals.
I Input signal to select PAL or NTSC mode of operation, pin set to Logic 1 selects PAL.
No Connect.
I Teletext Data Input Pin.
