... Note 1. SOT163-1; 1996 November 13. March 1991 GENERAL DESCRIPTION The SAA4700T is a bipolar integrated circuit designed for use in dataline receivers and incorporates a dataline slicer and decoder. The slicer extracts the dataline signal from the video signal and regenerates the data clock. It also ...

... The information in dataline 16 consists of fifteen 8-bit words; the total information content is shown in Table 1; and the organization of transmitted bytes is shown in Table 2. Out of the fifteen possible 8-bit words the SAA4700T extracts words 5 and 11 to 14. The contents of these words 2 can be read via the built-in I C-bus interface ...
