Programmable LUMA Delay GENERAL DESCRIPTION
ADV7174 integrated Digital Video Encoder that converts Digital CCIR-601 4:2:2 16-bit Component Video Data into standard analog baseband television signal compatible with world wide standards NTSC, B/D/G/H/I, This 4:2:2 data-stream interpolated into 4:4:4 Component Video (YUV Video interpolated times pixel rate. Color-Difference Components (UV) quadrature modulated using Sub-Carrier frequency generated on-chip synthesiser (also running times pixel rate times Pixel Rate sampling allows more accurate generation Sub-Carrier because Frequency Phase Errors reduced higher Sampling Rate. luminance chrominance components then digitally combined resulting Composite signal output 10Bit DAC. addition Composite output signal, there facility output S-VHS Video (10-Bits), Video (8-Bits). Y/C, format simultaneously available Analog Outputs with Composite Video Signal. Each Analog Output generates standard VideoLevel signal into Doubly Terminated load. ADV7174 also supports both NTSC square pixel mode slave mode.
Output Video Frames synchronised with incoming data Timing Reference Codes. Optionally Encoder accepts (and generate) HSYNC, VSYNC FIELD Timing Signals. These timing signals adjusted change pulse width position while part master mode. Encoder requires single times pixel rate MHz) Clock standard operation. Alternatively Encoder requires 24.54 Clock NTSC 29.5MHz Clock square pixel mode operation. internal clocks generated on-chip. Other features ADV7174 include internal color generator, lower power mode ability switch DACs individually. ADV7174 also provides color look table overlay video output. ADV7174 modes over wire serial bidirectional port (I2C Compatible) with slave addresses. ADV7174 fabricated CMOS process. monolithic CMOS construction ensures greater functionality with power dissipation. ADV7174 packaged 44-Pin thermally enhanced PQFP package (Patent pending). ADV7174 protected patents numbers 5,343,196 5,442,355 other intellectual property rights.

CAUTION (electrostatic discharge) sensitive device. Electrostatic charges high 4000 readily accumulate human body test equipment discharge without detection. Although ADV7174 features proprietary protection circuitry, permanent damage occur devices subjected high energy electrostatic discharges. Therefore, proper precautions recommended avoid performance degradation loss functionality.
