MAS3506D

The MAS3506D is the source decoder of Micronas StarMan chip set that is designed for the reception of WorldSpace signals. The MAS3506D extracts one Service Component (SC) of an incoming digital World-Space Broadcast Channel (BC) and decodes MPEG 1/2/2.5 Layer 3 encoded audio data contained in the selected Service Component.

Features of the MAS3506D are:(1)single-chip worldspace broadcast channel bitstream demultiplexer;(2)ISO MPEG 1/2/2.5 Layer 3 decoder;(3)ISO MPEG compliance tests passed;(4)data processing by a high-performance RISC DSP core (MASC);(5)download feature provides additional functionality;(6)self-synchronized operation;(7)output audio data delivered (in various formats) via an I2S bus (SDO);(8)digital volume control and stereo channel mixer;(9)automatic soft-mute function;(10)worldspace SCH-data output via I2C interface;(11)MPEG ancillary data provided via I2C interface;(12)status information accessible via PIO pins or I2C;(13):"CRC Error","MPEG Frame Synchronization" and "BC-Frame-Synchronization" indicators;(14):power management for reduced power consumption at lower sampling frequencies.

The absolute maximum ratings of the MAS3506D can be summarized as:(1):the parameter is ambient operating temperature,the symbol is TA,the rating is -40 to 85,the unit is ;(2):the parameter is storage temperature,the symbol is Ts,the rating is -40 to 125,the unit is ;(3):the parameter is power dissipation,the symbol is PMAX,the rating is 600,the unit is mW;(4):the parameter is supply voltage,the symbol is VSUP,the rating is 5.5,the unit is V;(5):the parameter is input voltage, all digital inputs,the symbol is VIdig,the rating is -0.3 to VSUP+0.3,the unit is V;(6):the parameter is input current, all digital inputs,the symbol is IIdig,the rating is -20 to +20,the unit is mA;(7):the parameter is current, all digital output,the symbol is IOUT,the rating is 0.5,the unit is A;(8):the parameter is current,the symbol is IOutDC,the rating is 1.5,the unit is A;(9):the parameter is input voltage, I2C-Pins,the symbol is VII2C,the rating is -0.3 to 5.5,the unit is V.
