Multimedia ICs QXpander™ processor QX2130FS / QX2130S The QX pander chip (QX-2000 Series) is a sound enhancement sound processor based on QSOUND's QX pander™ 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 •Speaker systems for desktop and notebook multimedia personal computers, televisions, audio equipment, video games and other devices •1)Features Virtual 3D sound from ordinary audio signals. 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 (45µVrms) 7) Low power consumption 8) Available in SSOP-A20 pin package or SDIP22 pin package. 2) No special encoding signals are necessary. 3) Three enhanced modes: QX1: Pro Listening QX2: Wide Listening QX3: Wow for Games VCC BIASOUT RCHIN CTRL1 CR1 CR2 CR3 CR4 RCHOUT POWERSAVE •Block diagram 20 19 18 17 16 15 14 13 12 11 VCC BIAS VIRTUAL AUDIO TM QXpander PROCESSOR 1 2 3 4 5 6 7 8 9 10 BIASIN MUTE LCHIN CTRL0 CL1 CL2 CL3 CL4 LCHOUT GND GND Note:The above diagram is for the QX2130FS (SSOP - A20 package) 1 Multimedia ICs QX2130FS / QX2130S •Absolute maximum ratings (Ta = 25°C) Parameter Power supply voltage Power dissipation Symbol Limits 13 VCC Pd Operating temperature Topr Storage temperature Tstg Unit V QX2130FS 1000∗1 QX2130S 750∗2 mW °C 0 ~ + 70 °C – 55 ~ + 125 ∗1 When mounted on a 90 × 50 × 1.6mm glass epoxy board Reduced by 10.0mW for each increase in Ta of 1°C over 25°C. ∗2 When mounted on a 90 × 50 × 1.6mm glass epoxy board Reduced by 7.5mW for each increase in Ta of 1°C over 25°C. •Recommended operating conditions (Ta = 25°C) Parameter Symbol Min.
