1 / 13 page Ordering number : EN5680 D3097HA(OT) No. 5680-1/13 Overview The LC7455A/M extracts the closed caption signal superimposed on a video signal during the vertical return period and, under the control of a clock signal provided by the decoder IC, transfers that signal to the IC (usually a microcontroller) that decodes the closed caption data. The LC7455A/M supports four operating modes. Modes 1 and 2 can be used for XDS. In these modes, the LC7455A/M, in combination with the decoder IC (microcontroller), extracts the caption signal superimposed on field 2 and uses it for NTSC VCR functions such as the automatic time and date setting function. In modes 3 and 4, the LC7455A/M, in combination with the decoder IC (microcontroller), extracts the caption signal superimposed on fields 1 and 2 and uses it for NTSC TV applications (mode 3) or PAL TV applications (mode 4). Functions • Low power dissipation achieved by fabrication in a CMOS process. • Stable caption signal extraction achieved by a built-in peak hold circuit and the use of digital technology. • Operating supply voltage: 5 V ±10% • Package LC7455A: 16-pin DIP LC7455M: 18-pin MFP Package Dimensions unit: mm 3006B-DIP16 unit: mm 3095-MFP18 SANYO: DIP16 [LC7455A] SANYO: MFP18 [LC7455M] LC7455A, 7455M SANYO Electric Co.,Ltd.
