1 Introduction
The ADC104 series of 10-bit analogue to digital converters are designed to convert
RGBS/YUVS signals to SDI serial digital video.
The range consists of the ADC104F which fully meets ITU 601 specifications for
component video filtering, the ADC104N which nearly meets the ITU 601 specification
and the ADC104FK, designed for use with graphics keys and which accepts only a Y and
sync input. The ADC104F and ADC104FK also provide eight test patterns.
