VSP 94x2A
Powerful Scan-Rate Converter
including Multistandard Color Decoder
Release Note: Revision bars indicate significant
changes to the previous edition.
1. Introduction
The VSP 94x2A (PRIMUS) is a new component of the
Micronas MEGAVISION
®
IC set in a CMOS embed-
ded DRAM technology. The VSP 94x2A comprises all
main functions of a digital featurebox in one monolithic
IC. The number of features is limited in favor of a low-
cost solution, but no trade-off has been made concern-
ing picture quality.

DATA SHEET
The family is ideally suited to work in conjunction with
the deflection processors SDA 9380 (9402/32) and
DDP 3315C (9412/42). In combination with the ’digital
TV decoder’ MDE 9500, double-scan iDTV is possible.
The package is upward pin-compatible to other
medium-range and high-end devices of the VSP 94xy
family. A 50/60 Hz derivative is also available (9432,
9442). The device comprises a digital multistandard
color decoder, an RGB interface with fast-blank capa-
bility (SCART), digital ITU656 input, scaling units
including panorama, embedded DRAM for upconver-
sion, picture improvements, temporal noise reduction,
as well as A/D and D/A converters.
