Function
Interrupt. This pin can be active low or active high. When SDP/CP status bits change,
this pin triggers. The set of events that triggers an interrupt is under user control.
HS is a Horizontal Synchronization Output Signal (SDP and CP modes). CS is a Digital
Composite Synchronization Signal (and can be selected while in CP mode).
Vertical Synchronization Output Signal (SDP and CP modes).
FIELD is a Field Synchronization Output Signal (all interlaced video modes). This
pin also can be enabled as a Data Enable signal (DE) in CP mode to allow direct
connection to a HDMI/DVI Tx IC.
I
SDA2 is the data line for the VBI readback port.
I
Control port and SCLK2 is the clock line for the VBI data readback port.
This pin selects the I
set to Logic 0 sets the address for a write to control port of 0x40 and the readback
address for the VBI port of 0x21. ALSB set to a logic high sets the address for a write to
control port of 0x42 and the readback address for the VBI port of 0x23.
System Reset Input. Active low. A minimum low reset pulse width of 5 ms is required
to reset the ADV7403 circuitry.
LLC1 is a line-locked output clock for the pixel data (range is 12.825 MHz to 140 MHz
for ADV7403KSTZ-140; 12.825 MHz to 110 MHz for ADV7403BSTZ-110.
Input Pin for 28.63636 MHz crystal, or can be overdriven by an external 3.3 V,
28.63636 MHz clock oscillator source to clock the ADV7403.
This pin should be connected to the 28.63636 MHz crystal or left as a no connect if an
external 3.3 V 28.63636 MHz clock oscillator source is used to clock the ADV7403. In
crystal mode the crystal must be a fundamental crystal.
The recommend external loop filter must be connected to this ELPF pin.
This pin should be left unconnected or alternaltely tie to AGND.
This pin should be left unconnected.
Subcarrier Frequency Lock (SFL). This pin contains a serial output stream, which can
be used to lock the subcarrier frequency when this decoder is connected to any
Analog Devices digital video encoder. SYNC_OUT is the sliced sync output signal
available only in CP mode.
Internal Voltage Reference Output.
Common-Mode Level Pin (CML) for the internal ADCs.
ADC Capacitor Network.
ADC Capacitor Network.
External Bias Setting Pin. Connect the recommended resistor (1.35 kΩ) between pin
and ground.
Can be configured in CP mode to be either a digital HS input signal or a digital CS
input signal used to extract timing in a 5-wire or 4-wire RGB mode.
VS Input Signal. Used in CP mode for 5-wire timing mode.
Data Enable Input Signal. Used in 24-bit digital input port mode (for example,
processing 24-bit RGB data from a DVI Rx IC).
Clock Input Signal. Used in 24-bit digital input mode (for example, processing 24-bit
RGB data from a DVI Rx IC) and also in digital CVBS input mode.
Sync on Green Input. Used in embedded sync mode.
Sync on Luma Input. Used in embedded sync mode.

C Port Serial Data Input/Output Pins. SDA1 is the data line for the control port, and
C Port Serial Clock Input (max clock rate of 400 kHz). SCLK1 is the clock line for the
