MITSUBISHI ICs (AV COMMON) M52393P/FP EDTV2 IDENTIFICATION SIGNAL DETECTOR DESCRIPTION The M52393 are integrated-circuits of a semiconductor, developed PIN CONFIGURATION (TOP VIEW) 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, 2.04M TRAP 1 16 VCC 2 15 VIDEO IN 3 14 3.58M TRAP COMP2 4 In order to satisfy demand, we have developed the EDTV2 CLAMP2 5 identification signal processing ICs that include all necessary COMP3 6 capabilities for detection (synchronous signal separation, line LINE CORRELATION SW GND 7 10 FRAME/FIELD SW 8 9 DET OUT ICs) with gate arrays. There was a great demand for ICs that enabled cost reduction. counter, filters, level detection, and bit judgment). The use of such M52393P/FP COMP1 CLAMP1 many manufacturers had to combine discrete components (non- 13 SYNC SEPA FILTER 12 V.SEPA FILTER 11 fSC IN ICs reduces parts, eliminates the need for complicated adjustment, Outline 16P4 16P2N-A and enables easy handling and 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).

However it detects during 3lines (including before and after 2 lines of the line can not be detected consecutivelly, a signal is not an EDTV2 one 22). A field contains the ID signal in its appropriate lines, whitch and the pin 9 is low. Detecting timing is varied in following 2 modes. results in an EDTV2 signal. In a case the ID signal is detected a couple of times during three A field mode lines, a signal is regarded as a standard signal not an EDTV2 The pin 10 is opened (2.5V). The detection is performed once a considering the correlation between 2 or 3 lines (pin 7 is grounded). field. It takes more than 133ms (4 frames) for the distinction. On the other hand, the line correlation is off by opening the pin 7. In this case, the signal is regerded as an EDTV2 even though the ID A frame mode signal is detected a couple of times during the three lines. The pin 10 is grounded (0V). The detection is performed once a frame; once a Odd field or once a Even field. It takes more than 267ms (8 frames) for the distinction. Note: The alternatvie of Odd or Even field is difficult because of no field distinction. 7 VIDEO IN Start of Even Field Even Field VIDEO IN Start of Odd Field Odd Field Vertical Blanking=20+1H 1 264 265 3 266 4 267 5 268 6 269 7 270 8 271 9 272 10 273 ∗ The EDTV2 ID Signal is detected in either Odd or Even field in a frame mode.
