6-Ch Audio Selector Tel: 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw PT2323 DESCRIPTION PT2323 is a 6-Channel Audio Selector utilizing CMOS Technology specially designed for Home Theater System. It provides a built-in 2-Channel to 6-Channel Translator, which can directly mix traditional stereo channel to simulate a 6-Channel audio output. Single power supply (9V), I2C Bus Interface as well as very low Total Harmonic Distortion (THD < 0.005%) and other features are incorporated into a single chip thereby providing very high performance. Pin assignments and application circuit are optimized for easy PCB layout and cost saving advantages. FEATURES Supply Voltage: 9V 4 Stereo Inputs One 6-Channel Input Maximum Input Voltage: 3.75Vrms (1KHz, THD<1%) Low Total Harmonic Distortion, THD<0.005% (1KHz, 0.2Vrms) Low Noise: No<4µVrms I2C Bus Interface Available in 28 Pins, DIP or SOP APPLICATIONS AV System Mini Compo Car Stereo Multi-Media Audio Systems PT2323 V1.3 -1- October, 2005 6-Ch Audio Selector BLOCK DIAGRAM 6CH IN FL CT SL FR SUB SR Tel: 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw PT2323 L1 L2 L3 L4 2CH ( St e re o ) IN R1 R2 R3 R4 MUTE FL 2CH ↓ 6CH Converter FL FR CT SU B SL SR 6CH Switch MUTE FR MUTE MUTE CT 6CH OUT SU B MUTE SL M IXO LPFI LPFO MUTE REF Control Unit + VCC GND SR SD A SC L I2C B US PT2323 V1.3 -2- October, 2005 6-Ch Audio Selector PIN CONFIGURATION L1 1 L2...
