The EVM analog audio output port provides options for AC/DC-coupled and filter or filter-less paths for easy evaluation. By default, the filter components are not populated.
Switch SW1 allows users to select respective loads for each output pair for 16 Ω, 604 Ω, or 10 kΩ if needed. These resistors are for quick evaluation and can be bypassed for actual load. SW1 and the output RCA connectors are located on the top left-hand side, shown in Figure 3-13.
OUT1 and OUT2 audio output pins have connection options with external load or the on-board load selections. A pair of RCA connectors, white from OUTP and red from OUTM, allow users to connect to external devices as differential or single-ended. Jumper header J36 or J37 must be populated if single-ended is desired or removed for differential configuration.
SW1 pin | Load Configuration | Resistor Rating | Output Module Register Setting |
---|---|---|---|
1, 4, 7, 10 | 16 Ω | 0.5 W | B0_P0_R101 |
2, 5, 8, 11 | 604 Ω | 0.125 W | B0_P0_R101 |
3, 6, 9, 12 | 10 kΩ | 0.4 W | B0_P0_R101 |
For TAC5411-Q1 or TAC5311-Q1, OUT2 components are not populated.
