| Multimedia ICs QXpanderTM processor QX2130FS / QX2130S The QX pander chip (QX-2000 Series) is a sound enhancement sound processor based on QSOUND's QX panderTM technology, and produces virtual 3D sound from ordinary audio signals. This IC requires no special encoding of input signals or additional speakers, and so simplifies the development of high-value-added personal computers, televisions and audio products. *Applications for desktop and notebook multimedia personal computers, televisions, audio equipment, video Speaker systems games and other devices *Features sound from ordinary audio signals. 1) Virtual 3D 2) No special encoding signals are necessary. 3) Three enhanced modes: QX1: Pro Listening QX2: Wide Listening QX3: Wow for Games 4) Internal functions for personal computers: power saver function, output muting function and stereo bypass function. 5) TTL-compatible control pins (at 5V). 6) Low noise (45Vrms) 7) Low power consumption 8) Available in SSOP-A20 pin package or SDIP22 pin package. *Block diagram POWERSAVE BIASOUT RCHOUT CTRL1 RCHIN CR1 CR2 CR3 CR4 VCC 20 VCC 19 18 17 16 15 14 13 12 11 BIAS VIRTUAL AUDIO TM QXpander PROCESSOR GND 1 BIASIN 2 MUTE 3 LCHIN 4 CTRL0 5 CL1 6 CL2 7 CL3 8 CL4 9 LCHOUT 10 GND Note:The above diagram is for the QX2130FS (SSOP - A20 package) 1 Multimedia ICs QX2130FS / QX2130S *Absolute maximum ratings (Ta = 25C) Parameter Power supply voltage Power dissipation Operating temperature Storage temperature Symbol VCC Pd Topr Limits 13 QX2130FS QX2130S 10001 7502 Unit V mW C C 0 ~ + 70 - 55 ~ + 125 Tstg 1 When mounted on a 90 x 50 x 1.6mm glass epoxy board Reduced by 10.0mW for each increase in Ta of 1C over 25C. 2 When mounted on a 90 x 50 x 1.6mm glass epoxy board Reduced by 7.5mW for each increase in Ta of 1C over 25C. *Recommended operating conditions (Ta = 25C) Parameter Operating power supply voltage Symbol VCC Min. 4.5 Typ. -- Max. 12.5 Unit V 2 Multimedia ICs QX2130FS / QX2130S *Input / output circuits (with QX2130FS) 1pin BIAS IN 2pin MUTE 3pin LCH IN 4pin CTRL0 5pin CL1 50k 5k 50k 30k 75k 2k 30k R R 6pin CL2 7pin CL3 8pin CL4 9pin LCH OUT 11pin POWER SAVE 50k R R R R R R R R 25k 50k 10k 10k 12pin RCH OUT 13pin CR4 14pin CR3 15pin CR2 16pin CR1 R 25k R R R R R R R R R pin17 CTRL1 18pin RCH IN 19pin BIAS OUT 2k 30k 75k 5k 3 Multimedia ICs QX2130FS / QX2130S *Analog characteristics (VCC = + 5V DC, GND = 0V DC, Ta = 25C) Parameter Supply current Supply current (QX mode) Supply current (stereo mode) Supply current (power saving mode) Maximum input level Maximum input level (QX3 mode) Maximum input level (QX2 mode) Maximum input level (QX1 mode) Maximum input level (stereo mode) Maximum output level Maximum mute level Maximum mute level (QX mode) Maximum mute level (stereo mode) Channel balance Output current Load resistance Load capacitance Input impedance Output impedance Distortion Distortion (QX3 mode) Distortion (QX2 mode) Distortion (QX1 mode) Distortion (stereo mode) Output noise voltage Output noise voltage (QX mode) Output noise voltage (stereo mode) Crosstalk Crosstalk (stereo mode) Symbol Min.
