LC75873NE

The LC75873NE is one member of the LC75873 family which is designed as the CMOS LSI that implements the singal processing and servo control required by compact disk players, laser disks, CD-V, CD-1 and related products. This device provides several types of signal processing to reduce the cost of CD player units, including demodulation of the optical pickup EFM signal, deinterleaving and error detection and corrention. It also processes a rich set of servo system commands sent from the control microprocessor.

Features of the LC75873NE are:(1)disc motor servocontroller;(2)laser focusing and tracking servocontroller;(3)track count and track jump functions;(4)16-bit stereo DAC serial interface;(5)CD-ROM serial interface;(6)EIAJ-format digital audio serial interface;(7)subcode bits and Q subcode outputs;(8)error detection and correction;(9)signal interpolation or previous-value hold if error correction fails;(10)+/-4 frames jitter tolerance;(11)single crystal for reference clock and all timing signals;(12)DEMO mode for automatic operation;(13)supports double-speed dubbing;(14)5 V supply;(15)64-pin QIP.

The absolute maximum ratings of the LC75873NE can be summarized as:(1)maximum supply voltage: Vss-0.3 to +7.0 V;(2)maximum input voltage: Vss-0.3 to VDD+0.3 V;(3)maximum output voltage: Vss-0.3 to VDD+0.3 V;(4)allowable power dissipation: 300 mW;(5)operating temperature: -30 to +75;(6)storage temperature: -40 to +125.
