16 / 103 page ![]() Introduction 7 SLES115 — August 2004 TAS5518 TERMINAL DESCRIPTION TERMIN- ATION 5-V TOLERANT I/O NO. DESCRIPTION TERMIN- ATION 5-V TOLERANT I/O NAME 28 SDIN4 DI 5 V Pulldown Serial audio data 4 input is one of the serial data input ports. SDIN4 supports four discrete (stereo) data formats and is capable of inputting data at 64 Fs. 29 SDIN3 DI 5 V Pulldown Serial audio data 3 input is one of the serial data input ports. SDIN3 supports four discrete (stereo) data formats and is capable of inputting data at 64 Fs. 30 SDIN2 DI 5 V Pulldown Serial audio data 2 input is one of the serial data input ports. SDIN2 supports four discrete (stereo) data formats and is capable of inputting data at 64 Fs. 31 SDIN1 DI 5 V Pulldown Serial audio data 1 input is one of the serial data input ports. SDIN1 supports four discrete (stereo) data formats and is capable of inputting data at 64 Fs. 32 PSVC O Power supply volume control PWM output 33 VR_DIG P Voltage reference for digital core supply 1.8 V. A pin-out of the internally regulated 1.8-V power used by digital core logic. A 0.47-µF low ESR capacitor should be connected between this terminal and DVSS. This terminal must not be used to power external devices 34 DVSS P Digital ground 35 DVSS P Digital ground 36 DVDD P 3.3-V digital power supply 37 BKND_ERR DI Pull up Active low. A backend error sequence is generated by applying logic low to this terminal. The BKND_ERR results in all system parameters unaffected, while all H-bridge drive signals going to a hard mute (M) state. 38 DVSS P Digital ground 39 VALID DO Output indicating validity of PWM outputs active high 40 PWM_M_1 DO PWM 1 output (differential −) 41 PWM_P_1 DO PWM 1 output (differential +) 42 PWM_M_2 DO PWM 2 output (differential −) 43 PWM_P_2 DO PWM 2 output (differential +) 44 PWM_M_3 DO PWM 3 output (differential −) 45 PWM_P_3 DO PWM 3 output (differential +) 46 PWM_M_4 DO PWM 4 output (differential −) 47 PWM_P_4 DO PWM 4 output (differential +) 48 VR_PWM P Voltage reference for digital PWM core supply 1.8 V. A pin-out of the internally regulated 1.8-V power used by digital PWM core logic. A 0.1-µF low ESR capacitor should be connected between this terminal and DVSS_PWM. This terminal must not be used to power external devices. 49 PWM_M_7 DO PWM 7 (Line out L) output (differential −) 50 PWM_P_7 DO PWM 7 (Line out L) output (differential +) 51 PWM_M_8 DO PWM 8 (Line out R) output (differential −) 52 PWM_P_8 DO PWM 8 (Line out R) output (differential +) 53 DVSS_PWM P Digital ground for PWM 54 DVDD_PWM P 3.3-V digital power supply for PWM 55 PWM_M_5 DO PWM 5 output (differential −) 56 PWM_P_5 DO PWM 5 output (differential +) 57 PWM_M_6 DO PWM 6 output (differential −) 58 PWM_P_6 DO PWM 6 output (differential +) 59 PWM_HPML DO PWM left channel headphone (differential −) 60 PWM_HPPL DO PWM left channel headphone (differential +) 61 PWM_HPMR DO PWM right channel headphone (differential −) 62 PWM_HPPR DO PWM right channel headphone (differential +) |
