Abstract
A highly integrated compact disc (CD) decoder is described. The chip contains all the decoding functions, digital filtering, bit-stream stereo digital-to-analog (D/A) conversion, and analog post-filtering. The design makes use of a CMOS process that results in its having a single 5-V supply, an extended operating temperature range, and low power consumption to make the IC suitable for portable and inexpensive applications. The chip contains circuitry for CD-decoding, programmable motor control, digital filtering, microcomputer interfacing, and switch capacitor network for stereo right and left channels. The 80-pin QFP packaged IC can withstand an extended temperature range of -40 degrees C to +85 degrees C.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
