LC78840M

The LC78840M is designed as one kind of four-times or eight-times oversampling digital filter that belongs to the LC78840 family. This device can be used in broadcast satellite (BS), compact disc (CD) and digital audio tape (DAT) applications. This device also operates at 384fs, 392fs, or 512fs, and has internal deemphasis for fs=32, 44.1 or 48 kHz. Output data length is 18 or 16 bits for right-times or four-times oversampling, respectively. And it operates from a 5 V supply and is available in 24-pin MFPs.

Features of the LC78840M are:(1)four-times or right-times oversampling;(2)384fs, 392fs, and 512fs operation;(3)double-rate compatible;(4)selectable deemphasis;(5)digital attenuator;(6)optional output offset;(7)two input and output formats;(8)5 V supply;(9)24-pin MFP.

The absolute maximum ratings of the LC78840M can be summarized as:(1)supply voltage range: -0.3 to 7.0 V;(2)input voltage range: -0.3 to VDD+0.3 V;(3)output voltage range: -0.3 to VDD+0.3 V;(4)operating temperature range: -30 to +75;(5)storage temperature range: -40 to +125.
