Preliminary R2S15903SP Sound Controller with Surround & AGC REJ03F0159-0140 Rev.1.4 Dec 06, 2005 Description The R2S15903SP is an optimum audio signal processor IC for TV. It has a 5ch input selector, AGC, surround/pseudo stereo, tone control(2band), output gain control and 2ch master volume. It can control all of these functions with I2C bus. Features • Volume: 0 to –89dB, –∞/ 1dB step. Each channel is independence control. 5 input selector + MUTE 2 Rec output (0/–2dB) Auto gain control (AGC level 4step) Tone control Bass: –15dB to +15dB/ 1dB step Treble: –15dB to +15dB/ 1dB step Surround / Pseudo stereo Mode selector: Bypass/ Tone / Tone & Pseudo Stereo or Surround Output gain control: 0dB/ +4.5dB I2C-BUS control Recommended Operating Condition Supply voltage: VCC = 9.0V(typ) Application TV, Mini Stereo, etc. System Configuration REC L1 REC L2 (IN L4) (IN L5) VCC=9V R2S15903SP Volume L Mode selector IN L1 IN L2 IN L3 AGC Tone Control (Bass / Treble) Volume R LOUT Pseudo Stereo and Surround Output Gain Control Mode Selector IN R1 IN R2 IN R3 ROUT Output Gain Control I C-BUS I/F REC R1 REC R2 (IN R4) (IN R5) SCL SDA 2 Rev.1.4 Dec 06, 2005 page 1 of 11 R2S15903SP Preliminary Block Diagram and Pin Configuration REFIN 1 INL1 INL2 INL3 2 3 + Input Selector REF 32 VCC Input Selector 31 INR1 30 INR2 0/-2dB 0/-2dB 4 29 INR3 28 27 AGC RECR1 (INR4) RECR2 (INR5) RECL1 5 (INL4) RECL2 6 (INL5) CAGC1 7 AGCLOUT 8 Lch Volume 0~-89dB,-∞ Rch Volume 0~-89dB,- ∞ 26 CAGC2 25 AGCROUT 24 VOLINR 23 TRER VOLINL 9 TREL 10 Tone Control Bass/ Treble BASSL2 11 BASSL2 12 LOUT 13 PSEUDO 14 Rext 15 Pseudo Stereo and Surround Tone Control Bass/ Treble 22 BASSR2 21 BASSR2 20 ROUT Mode Selector Output Gain Control Mode Selector Output Gain Control + – De-pop + – 19 GND 18 SCL I 2 C-BUS I/F Cext 16 17 SDA Rev.1.4 Dec 06, 2005 page 2 of 11 R2S15903SP Preliminary Application Example VCC=9V 1μF + 1 2 3 4 5 6 7 8 1μF + – REF 32 Input Selector INL1 1μF + + + + 31 30 + + 1μF INR1 INR2 INR3 RECR1 (INR4) RECR2 (INR5) 33μF 1μF INL2 1μF Input Selector 0/-2dB 0/-2dB INL3 29 28 27 AGC 26 25 Lch Volume 0~-89dB,- ∞ Rch Volume 0~-89dB,-∞ + + + 1μF RECL1 (INL4) RECL2 (INL5) 4.7μF 4.7μF 4.7μF + + 4.7μF 1μF + 1MΩ 2.2μF + + 2.2μF 9 8200pF 24 8200pF 10 0.068μF 8.2kΩ 0.068μF Tone Control Bass/ Treble 23 Pseudo Stereo and Surround Tone Control Bass/ Treble 11 12 22 21 20 0.068μF 8.2kΩ 0.068μF LOUT 47kΩ + – 4.7μF 13 14 Output Gain Control Mode Selector Mode Selector + 4.7μF 47kΩ ROUT + + Output Gain Control – 19 SCL 0.015μF 15 10kΩ De-pop 18 I C-BUS I/F 2 SDA MCU 16 0.22μF 17 Rev.1.4 Dec 06, 2005 page 3 of 11 R2S15903SP Preliminary Absolute Maximum Ratings Parameter Power supply Power dissipation Thermal derating Operating temperature Stor […]
