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.

FEATURES

• All necessary detection capabilities, such as a synchronous signal separation circuit, are integrated into a single microchip. The use of the microchip can simplify application circuits, and eliminate the need for adjustment. (Only two inputs are provided: video signal input and fsc signal input.)

• Our original method is used for distinguishing EDTV2 identification 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).

APPLICATION

TV and videocassette recorder compatible with EDTV2.
