Table 2-9 shows DS160PR810EVM upstream devices controls that affect US1-US2 devices on the board.
| COMPONENT | NAME | FUNCTION / DESCRIPTION |
|---|---|---|
| J21 | 3x2 Header | Gain Controls tied to GAIN pins of all upstream device banks L0: -6 dB Gain Setting L1: -3 dB Gain Setting L2: 3 dB Gain Setting L3: 0 dB Gain Setting (default) |
| J22 | 12x2 | Pin Mode: EQ1 controls for each upstream device and device bank. Use pins 1–6 for configuring EQ1_0 pin of Bank 0 of US1 device. Use pins 7–12 for configuring EQ1_1 pin of Bank 1 of US1 device. Use pins 13–18 for configuring EQ1_0 pin of Bank 0 of US2 device. Use pins 19–24 for configuring EQ1_1 pin of Bank 1 of US2 device. SMBus, I2C Modes: ADDR1 controls for each upstream device. Use pins 1–6 for configuring ADDR1 pin of US1 device. Use pins 13–18 for configuring ADDR1 pin of US2 device. Install a shunt to achieve L0, L1, or L2 level on the pin. Leave floating to achieve L3 level on the pin. |
| J23 | 12x2 Header | Pin Mode: EQ0 controls for each upstream device and device bank. Use pins 1–6 for configuring EQ0_0 pin of Bank 0 of US1 device. Use pins 7–12 for configuring EQ0_1 pin of Bank 1 of US1 device. Use pins 13–18 for configuring EQ0_0 pin of Bank 0 of US2 device. Use pins 19–24 for configuring EQ0_1 pin of Bank 1 of US2 device. SMBus, I2C Modes: ADDR0 controls for each upstream device. Use pins 1–6 for configuring ADDR0 pin of US1 device. Use pins 13–18 for configuring ADDR0 pin of US2 device. Install a shunt to achieve L0, L1, or L2 level on the pin. Leave floating to achieve L3 level on the pin. |
| J24 | 3x1 Header | GAIN / SDA Dual Function Pin Provision for US1 Device Install shunt across pins 1-2 for operation in Pin Mode (default) Install shunt across pins 2-3 for operation in SMBus, I2C Modes |
| J25 | 3x1 Header | RX DET / SCL Dual Function Pin Provision for US1 Device Install shunt across pins 1-2 for operation in Pin Mode (default) Install shunt across pins 2-3 for operation in SMBus, I2C Modes |
| J26 | 3x1 Header | GAIN / SDA Dual Function Pin Provision for US2 Device Install shunt across pins 1-2 for operation in Pin Mode (default) Install shunt across pins 2-3 for operation in SMBus, I2C Modes |
J27 | 3x1 Header | RX DET / SCL Dual Function Pin Provision for US2 Device Install shunt across pins 1-2 for operation in Pin Mode (default) Install shunt across pins 2-3 for operation in SMBus, I2C Modes |
