General Description
The SDA 9402 (PRIMUS) is a new component of the Micronas MEGAVISION® IC set in a copper CMOS embedded DRAM technology. The SDA 9402 comprises all main functions of a digital featurebox in one monolithic IC. The amount of features is limited in favour of a low-cost solution. But no trade-off has been made concerning picture quality. It is ideally suited to work in conjunction with the ’enhanced digital deflection processor’ SDA 9380. The package is pin upward compatible to other medium-range and high end devices of the SDA940X family. A 50/60Hz derivative is also available (SDA9402S).
