Overview
The LC7871E and LC7871NE are CMOS LSIs that integrate the signal processing functions required for compact disk extended graphics (CD-EG) decoding in a single chip. These products accept the R to W subcode signals output by CDP-DSP products such as the LC7860KA, LC7867E, LC7868E, LC7869E, or LC78681E, and perform de-interleaving, error detection and correction, graphics instruction processing, and image processing.

Features
• A CD-G decoder can be constructed from only two chips, since no controller is required.
• A CD-EG decoder can be constructed with the addition of two 256-kbit DRAMs since no controller is required.
• Silicon gate CMOS process for low power dissipation
• 5 V single voltage power supply
