SAA5667HL/M1

Product Summary

The SAA5667HL/M1 is an enhanced TV microcontroller with on-screen display (OSD). The SAA5667HL/M1 is intended for use as the central control mechanism in a television receiver. The SAA5667HL/M1 provides control functions for the television system, OSD and incorporate an integrated Data Capture and display function for either Teletext or Closed Caption. The SAA5667HL/M1 offers all the features from the SAA56xx family with the addition of support for a range of Progressive Scan display modes.
