GENERAL DESCRIPTION

The STV0118 is a high performance PAL/NTSC digital encoder in a low cost pakage. It converts a 4:2:2 digital video stream into a standard analog baseband PAL/NTSC signal and into RGB analog components. The STV0118 can handle interlaced mode (with 525/625 line standards) and non-interlaced mode. It can perform Closed-Captions, CGMS or Teletext encoding.

■ NTSC-M, PAL-B, D, G, H, I, N, M, PLUS NTSC-4.43 ENCODING (OPTIONAL PEDESTAL IN ALL STANDARDS)

■ SMALL AND ECONOMICAL SO28 PACKAGE

■ LINE SKIP/INSERT CAPABILITY SUPPRESSING THE NEED FOR AN EXTERNAL VCXO, THUS REDUCING APPLICATION COST

■ 4 SIMULTANEOUS ANALOG OUTPUTS : RGB+ CVBS,or S-VHS (Y/C)+ CVBS1 + CVBS2

■ 54MHz INPUT MULTIPLEX INTERFACE FOR DOUBLE ENCODING APPLICATIONS (TO BE ABLE TO ENCODE OR NOT THE OSD CONTENT OF THE VIDEO INPUT STREAM)

■ CROSS-COLOR REDUCTION BY SPECIFIC TRAP FILTERING ON LUMA WITHIN CVBS FLOW

■ CLOSED CAPTIONING, CGMS ENCODING AND TELETEXT ENCODING

■ ITU-R/CCIR601 ENCODING WITH EASILY PROGRAMMABLE COLOR SUB-CARRIER FREQUENCIES

■ DIGITAL FRAME SYNC INPUT/OUTPUT (ODDEV/VSYNC), PROGRAMMABLE POLARITY AND RELATIVE POSITION

■ DIGITAL HORIZONTAL SYNC INPUT/OUPUT (HSYNC), PROGRAMMABLE POLARITY AND RELATIVE POSITION
