ZHCSRJ6D June 2010 – October 2024 TLV320AIC3104-Q1
PRODUCTION DATA
Programming the TLV320AIC3104-Q1 to passive analog bypass occurs by configuring the output stage switches for passthrough. This is done by opening switches SW-L0, SW-L3, SW-R0, and SW-R3 and closing SW-L1 and SW-R1. See Figure 7-12. Programming this mode is done by writing to page 0, register 108.
Connecting the MIC1LP/LINE1LP input signal to the LEFT_LOP pin is done by closing SW-L1 and opening SWL0; this action is done by writing a 1 to page 0, register 108, bit D0. Connecting the MIC1LM/LINE1LM input signal to the LEFT_LOM pin is done by closing SW-L4 and opening SW-L3; this action is done by writing a 1 to page 0, register 108, bit D1.
Connecting the MIC1RP/LINE1RP input signal to the RIGHT_LOP pin is done by closing SW-R1 and opening SW-R0; this action is done by writing a 1 to page 0, register 108, bit D4. Connecting MIC1RM/LINE1RM input signal to the RIGHT_LOM pin is done by closing SW-R4 and opening SW-R3; this action is done by writing a 1 to page 0, register 108, bit D5. A diagram of the passive analog bypass mode configuration is shown in Figure 7-12.
In general, connecting two switches to the same output pin should be avoided, as this error shorts two input signals together, and would likely cause distortion of the signal as the two signals are in contention. Poor frequency response would also likely occur.
