33 / 93 page  ALC5610 Datasheet AC’97 Audio Codec + Touch Panel Controller + Voice PCM Interface 24 Track ID: JATR-1076-21 Rev. 1.4 7.8. Analog Audio Output Data Path The ALC5610 supports three Analog Audio output paths: • SPK_OUT_L/R • HP_OUT_L/R • MONO_OUT 7.8.1. Speaker Output SPK_OUT_L/R provides two-channel differential output. The SPK_OUT_L source is set in Reg1C[15:14]. Sources are shown below: • Vmid • Headphone left mixer • Speaker mixer • MONO mixer The SPK_OUT_R source is set in Reg1C[12:11]. Sources are shown below: • Vmid • Headphone right mixer • Speaker mixer • MONO mixer The ALC5610 speaker supports Class-AB and Class-D type amplifiers (set in Reg1C[13]:spk_out_sel). As the voltage of SPKVDD is usually higher than AVDD, the driver should set the Class-AB Vmid ratio in Reg40[5:3], and the Class-D Vmid ratio in Reg40[7:6] in order to extend the output level. In Class-AB mode, for L+R MONO speaker solutions, SPK_OUT_R can select a different signal source (SPKR Volume output or SPKL Volume output by Reg1C[14]) but SPK_OUT_RN only outputs SPKR Volume Negative Output. The SPK_OUT_L/R volume and mute are controlled by Reg02. Reg3E[13:12] and Reg3E[9:8] can be used to power down SPK output. Reg3C[14]: pow_clsab is used to power down Class-AB output. SPK_OUT_L/R supports the zero-cross detect function (enabled at Reg02[6][14]: sp_l_dezero/ sp_r_dezero). |
