Datasheet
DESCRIPTION
The M52393 are integrated-circuits of a semiconductor, developed
especially for EDTV2 identification signal detection.
In contrast to such ICs, few products on the IC market had the
simple function of detecting identification signals. For that purpose,
many manufacturers had to combine discrete components (non-
ICs) with gate arrays. There was a great demand for ICs that
enabled cost reduction.
In order to satisfy demand, we have developed the EDTV2
identification signal processing ICs that include all necessary
capabilities for detection (synchronous signal separation, line
counter, filters, level detection, and bit judgment). The use of such
ICs reduces parts, eliminates the need for complicated adjustment,
and enables easy handling and cost reduction.
FEATURES
1
BLOCK DIAGRAM
All necessary detection capabilities, such as a synchronous sig-
nal separation circuit, are integrated into a single microchip. The
use of the microchip can simplify application circuits, and elimi-
nate the need for adjustment. (Only two inputs are provided:
video signal input and fsc signal input.)
Our original method is used for distinguishing EDTV2 identifica-
tion signals from normal video signals.
Therefore the accuracy of identification is improved.
The detection level is adjustable.
The microchip operates on a single supply voltage of 5V.
Two types of packages are provided:
DIP with a lead pitch of 2.54mm (M52393P); and SOP with a
pitch of 1.27mm (M52393FP).
