LC7938C

The LC7938C is designed as one kind of digital signal processor for compact disc player that can be used in compact disk players, laser disk players, CD-V, CD-I and similar applications. This device provides a rich set of signal processing functions, including demodulation of the EFM signal from the optical piackup, de-interleaving, error detection and correction and digital filter functions that can process servo system commands sent from a control microprocessor.

Features of the LC7938C are:(1)64-pin QFP (miniature, reduced space package);(2)silicon gate CMOS process (low power);(3)provision of a DEMO pin eases the manufacturing processes associated with adjustment steps;(4)low voltage operation.

The absolute maximum ratings of the LC7938C can be summarized as:(1)data setup time: 400 ns;(2)data hold time: 400 ns;(3)high level clock pulse width: 400 ns;(4)low level clock pulse width: 400 ns;(5)data read acess time: 0 to 400 ns;(6)command transfer time: 1000 ns.
