Overview
DESCRIPTION The PT2037 is a multiple functions audio signal processor, very low distortion and low noise are obtained by the advanced CMOS fabricate technology.
All of characteristics and functions are designed for the customer who needs high performance and better hearing experience.
This device provides a lot of new features like soft-mute and zero-crossing mute to minimize the noises during the audio sources are switching.
Further more, the device equipped differential audio inputs to improve the Common Mode Reject Ratio and it is very helpful to canceling ground loop hum noises in the car and audio dock system.
APPLICATIONS • Car audio • Audio dock system • Mini compo system BLOCK DIAGRAM PT2037 Digitally Controlled Audio Processor FEATURES • Input multiplexer - 4 Stereo input - 1 Mono input - 1 Differential input - Selectable input gain for optimal adaptation to different sources • Multiple MUTE function - Software controlled: Direct Mute, Zero-Crossing Mute and Soft Mute - Hardware controlled: Soft Mute • Fully programmable loudness function • Volume control in 1dB steps including gain up to 16dB • 3 band (Bass, Middle and Treble ) tone control • Four independent speaker attenuators control in 1dB steps for balance and fader facilities • Programmable threshold for pause and zero cross mute detector • All functions programmable via serial I2C bus BASS_LI BASS_LO MID_LI MID_LO TREB_L LOUD_L IN_L MUXOUT_L STEREO1_L STEREO2_L STEREO3_L STEREO4_L DIFF_L DIFFGND_L MONO STEREO1_R STEREO2_R STEREO3_R STEREO4_R DIFF_R DIFFGND_R DVDD AVDD 16 17 18 15 14 13 11 8 9 10 7 6 5 41 42 SUPPLY INPUT MULTIPLEXER 21 20 12 IN GAIN VOLUME +LOUDN IN GAIN VOLUME +LOUDN 43 39 3 24 44 30 31 25 24 TREBLE MIDDLE BASS SOFT MUTE I2C BUS DECODER +LATCHES SPEAKER ATT 34 OUT_LF SPEAKER ATT 33 OUT_LR 40 ADDR 38 SCL 37 SDA 36 DGND TREBLE MIDDLE BASS SOFT MUTE SPEAKER ATT 29 OUT_RR SPEAKER ATT 32 OUT_RF MUTE CONTROL SOFT,ZERO 1 23 22 27 26 28 35 19 CSM PAUSE...
