Lt/Rt is also suitable for stereophonic sound playback on a hi-fi or on headphones. where Ls and Rs are phase shifted 90° (5) 3.11.2 Left Only/Right Only (Lo/Ro) Lo/Ro is a downmix suitable when mono compatibility is required. Lo/Ro destroys front/rear channel separation information and thus a Dolby Pro Logic upmixer will not be able to properly extract 5.1 channels again. where att = –3 dB, –6 dB, –9 dB or 0 dB (6) 3.12 Output Mixer The TAS5548 provides an 8×2 output mixer for channels 1, 2, 3, 4, 5, and 6. For channels 7 and 8, the TAS5548 provides an 8×3 output mixer. These mixers allow each output to be any mix of any two (or three) signal-processed channels. The control parameters for the output crossbar mixer are programmable via the I2C interface. All of the TAS5548 features are available when the 8×2 and 8×3 output mixers are configured in the pass-through output mixer configuration, where the audio data from each DAP channel maps directly to the corresponding PWM channel (i.e., DAP channel 1 to PWM channel 1, etc). When mixing or remapping DAP channels to different PWM output channels there are limitations to consider: • Individual channel mute should not be used. • The sum of the minimum channel volume and master volume should not be below –109 dB. 32 TAS5548 DAP Architecture Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TAS5548 |
