GENERAL DESCRIPTION
The ADV7184 integrated video decoder automatically detects
and converts a standard analog baseband television signal,
which is compatible with worldwide standards NTSC, PAL,
and SECAM, into 4:2:2 component video data-compatible
with 16-bit or 8-bit CCIR601/CCIR656.
The advanced and highly flexible digital output interface
enables performance video decoding and conversion in line-
locked clock-based systems. This makes the device ideally
suited for a broad range of applications with diverse analog video
characteristics, including tape-based sources, broadcast sources,
security and surveillance cameras, and professional systems.
The 10-bit accurate ADC provides professional quality video
performance and is unmatched. This allows true 8-bit
resolution in the 8-bit output mode.
The 12 analog input channels accept standard composite,
S-Video, and YPrPb video signals in an extensive number of
combinations.
AGC and clamp restore circuitry allow an input video signal
peak-to-peak range of 0.5 V to 1.6 V. Alternatively, these can be
bypassed for manual settings.
The fixed 54 MHz clocking of the ADCs and datapath for all
modes allows very precise, accurate sampling and digital
filtering. The line locked clock output allows the output data
rate, timing signals, and output clock signals to be synchronous,
asynchronous, or line locked even with ±5% line length
variation. The output control signals allow glueless interface
connections in almost any application. The ADV7184 modes
are set up over a 2-wire, serial, bidirectional port (I
2
C-
compatible).
SCART and overlay functionality are enabled by the ADV7184’s
ability to simultaneously process CVBS and standard definition
RGB signals. Signal mixing is controlled by the fast blank pin.
The ADV7184 is fabricated in a 3.3 V CMOS process. Its
monolithic CMOS construction ensures greater functionality
with lower power dissipation. The ADV7184 is packaged in a
small 80-lead LQFP Pb-free package.
