HI3050  
Triple 10-Bit, 50 MSPS,  
High Speed, 3-Channel D/A Converter  
August 1997  
Features  
Description  
The HI3050 is a triple, 10-bit D/A converter, fabricated in a  
silicon gate CMOS process, ideally suited for RGB video  
applications.  
• Resolution . . . . . . . . . . . . . . . . . . . . . . . . . .Triple 10-Bit  
• Throughput Rate . . . . . . . . . . . . . . . . . . . . . . . . . 50MHz  
• 3-Channel, RGB, I/O  
The converter incorporates three 10-bit input data registers  
with a common blanking capability, forcing all outputs to 0mA.  
The HI3050 features low glitch, high impedance current out-  
• RS-343A/RS-170 Compatible Outputs  
• Low Power Consumption (Typ) . . . . . . . . . . . . .500mW puts and single 5V supply operation. Low current inputs  
accept standard TTL/CMOS levels. The architecture is a  
current cell arrangement providing low differential and integral  
• Differential Linearity Error . . . . . . . . . . . . . . . ±0.5 LSB  
linearity errors.  
• Low Glitch Energy  
The HI3050 requires a 2V external reference and a set  
resistor to control the output current. The HI3050 also features  
a chip enable/disable pin for reducing power consumption  
(<5mW) when the part is not in use.  
• CMOS Compatible Inputs  
• Direct Replacement for Sony CXD2308  
Applications  
The HI3050 can generate RS-343A and RS-170 compatible  
video signals into doubly terminated and singly terminated  
75loads.  
• NTSC, PAL, SECAM Displays  
• High Definition Television (HDTV)  
• Presentation and Broadcast Video  
• Image Processing
