PT2358 9 Inputs, 7 Outputs Car Audio Processor DESCRIPTION The PT2358 is a multiple inputs audio processor designed for Car Audio purpose. Using I2C interface controls all of the functions. Thanks for highly integration most of peripheral sub-circuits and components, it provides up to 9 inputs and equips outputs includes front, rear channel outputs. For highly enhanced audio performance and experience, PT2358 volume controller has Soft-Step function to eliminate click noise during volume step changes. Adjustable input gain, adaptive loudness, subwoofer filter, treble and bass tone control are all included. APPLICATIONS  Car Audio FEATURES  Operation voltage 6~10V  7 single-ended stereo Inputs  1 quasi-differential (QD) input for AUX  1 fully-differential (FD) input for Bluetooth® audio module.  Input gain from 0 ~+15dB in 1dB step  Main volume gain from +15 to -79dB in 1dB step with Soft-Step function.  Soft-Mute and Soft-Step function for preventing audible click during volume and sources changing.  1 subwoofer output with 3-band crossover frequency selection and gain from +15 to -79dB in 1dB step  Tone Control (Bass and Treble): -15 to +15dB in 1dB step  Loudness: gain from 0 to -15dB in 1dB step  Mixing input with 50% mixing ratio for front speakers, gain from -79 to +15dB in 1dB step.  4 independent outputs for front and rear speakers, output gain from +15 to -79dB with 1dB step  Controlled by I²C Interface  Low Distortion and Low Noise  48-pin LQFP package Tel: 886-66296288‧Fax: 886-29174598‧http://www.princeton.com.tw‧2F, 233-1, Baociao Road, SindianDist.,New Taipei City 23145, Taiwan PT2358 BLOCK DIAGRAM MIXIN SE7L SE6L SE5L SE4L SE3L SE2L SE1L FDL+ FDL- FDRFDR+ QDL QDG QDR FDL L FDR R L QD R SDA CONTROL SCL SE7R SE6R SE5R SE4R SE3R SE2R SE1R IN GAIN LOUDNESS SOFT-MUTE MASTER VOLUME BASS TREBLE IGL VOL LDL REF IN GAIN BL1 BL2 TRL REF VDD CREF GND POWER REF IN GAIN L+R MIX C1P FLAT RSW1 RSW2 C2 LPF SOUT SIN LOUDNESS SOFT-MUTE MASTER VOLUME BASS TREBLE IGR VOR LDR REF IN GAIN BR1 BR2 TRR REF L-MIX ON R-MIX ON OUTLF OUTRF OUTLR OUTSW OUTRR V1.0 2 August 2014 APPLICATION CIRCUIT VDD 9V 4.7uF 0.1uF SE7R SE7L 2.2uF 2.2uF MCU SE6R SE6L SE5R SE5L SE4R SE4L SE3R SE3L SE2R SE2L SE1R SE1L Bluetooth Audio Module 2 1 3 FDR+ FDRFDLFDL+ QDR QDG QDL 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 2.2uF 37 SE6R 38 SE6L 39 SE5R 40 SE5L 41 SE4R 42 SE4L 43 SE3R 44 SE3L 45 SE2R 46 SE2L 47 SE1R 48 SE1L 10uF PT2358 1 FDR+ 2 FDR3 FDL4 FDL+ 5 QDR 6 QDG 7 QDL 8 VOL 9 IGL 10 LDL 11 LDR 12 IGR SE7L 36 SE7R 35 SDA 34 SCL 33 GND 32 CREF 31 VDD 30 MIXIN 29 OUTLF 28 OUTLR 27 OUTRR 26 OUTRF 25 1uF 4.7uF 4.7uF 4.7uF 4.7uF MIX IN 47nF 47nF 2.2uF PT2358 OUTLF OUTLR OUTRR OUTRF OUTSW 24 SOUT 23 SIN 22 C2 21 C1P 20 TRL 19 TRR 18 BR1 17 BR2 16 BL1 15 BL2 14 VOR 13 4.7uF 2.2uF OUTSW 27nF 68nF 8.2nF 8.2nF 100nF 100nF 100nF 100nF 2.2nF 4.7K 4.7K V1.0 3 August 2014 SE7L 36 SE7R 35 SDA 34 SCL 33 GND 32 CREF 31 VDD 30 MIXIN 29 OUTLF 28 OUTLR 27 OUTRR 26 OUTRF 25 ORDER INFORMATION Valid Part Number PT2358 Package Type 48-Pin, LQFP PIN CONFIGURATION 37 SE6R 38 SE6L 39 SE5R 40 SE5L 41 SE4R 42 SE4L 43 SE3R 44 SE3L 45 SE2R 46 SE2L 47 SE1R 48 SE1L PT2358 PT2358 Top Code PT2358-LQ OUTSW 24 SOUT 23 SIN 22 C2 21 C1P 20 TRL 19 TRR 18 BR1 17 BR2 16 BL1 15 BL2 14 VOR 13 1 FDR+ 2 FDR3 FDL4 FDL+ 5 QDR 6 QDG 7 QDL 8 VOL 9 IGL 10 LDL 11 LDR 12 IGR V1.0 4 August 2014 PT2358 IMPORTANT NOTICE Princeton Technology Corporation (PTC) reserves the right to make corrections, modifications, enhancements, improvements, and other changes to its products and to discontinue any product without notice at any time.
