Description  
The TMC2490A video encoder converts digital component  
video (in 8-bit parallel CCIR-601/656 or ANSI/SMPTE  
125M format) into a standard analog baseband television  
(NTSC, NTSC-EIA, and all PAL standards) signal with a  
modulated color subcarrier. Both composite (single lead) and  
S-Video (separate chroma and luma) formats are active  
simultaneously at all three analog outputs. Each video output  
generates a standard video signal capable of driving a singly-  
or doubly-terminated 75 Ohm load.  
The TMC2490A is intended for all non-Macrovision  
encoder applications.  
• Single +5V power supply  
• 44 lead PLCC package  
• Parallel and serial control interface  
The TMC2490A is fabricated in a submicron CMOS  
process and is packaged in a 44-lead PLCC. Performance is  
guaranteed over the full 0°C to 70°C operating temperature  
range.
