M52393FP

MITSUBISHI ICs (AV COMMON) M52393P/FP EDTV2 IDENTIFICATION SIGNAL DETECTOR 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 (nonICs) 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.

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.)
