Table 2-8 shows the DS320PR810EVM downstream device controls that affect DS1 and DS2 devices on the board.
| COMPONENT | NAME | FUNCTION / DESCRIPTION |
|---|---|---|
| J14 | 4x2 Header | Gain Controls tied to GAIN pins of all downstream
device banks L0: –6 dB Gain Setting L1: –4 dB Gain Setting L2: -2 dB Gain Setting L3: +2 dB Gain Setting L4: 0 dB Gain Setting (default) |
| J15 | 17x2 Header | Pin Mode: EQ1 controls for each downstream device and device bank. Use pins 1–8 for configuring EQ1_0 pin of Bank 0 of DS1 device. Use pins 9–16 for configuring EQ1_1 pin of Bank 1 of DS1 device. Use pins 17–24 for configuring EQ1_0 pin of Bank 0 of DS2 device. Use pins 25–32 for configuring EQ1_1 pin of Bank 1 of DS2 device. SMBus, I2C Modes: ADDR1 controls for each downstream device. Use pins 1–8 for configuring ADDR1 pin of DS1 device. Use pins 17–24 for configuring ADDR1 pin of DS2 device. Install a shunt to achieve L0, L1, L2 or L3 level on the pin. Leave floating to achieve L4 level on the pin. |
| J16 | 17x2 Header | Pin Mode: EQ0 controls for each downstream device and device bank. Use pins 1–8 for configuring EQ0_0 pin of Bank 0 of DS1 device. Use pins 9–16 for configuring EQ0_1 pin of Bank 1 of DS1 device. Use pins 17–24 for configuring EQ0_0 pin of Bank 0 of DS2 device. Use pins 25–32 for configuring EQ0_1 pin of Bank 1 of DS2 device. SMBus, I2C Modes: ADDR0 controls for each downstream device. Use pins 1–8 for configuring ADDR0 pin of DS1 device. Use pins 17–24 for configuring ADDR0 pin of DS2 device. Install a shunt to achieve L0, L1, L2 or L3 level on the pin. Leave floating to achieve L4 level on the pin. |
| J17 | 3x1 Header | GAIN / SDA Dual Function Pin Provision for DS1 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 |
| J18 | 3x1 Header | RX DET / SCL Dual Function Pin Provision for DS1 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 |
| J19 | 3x1 Header | GAIN / SDA Dual Function Pin Provision for DS2 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 |
| J20 | 3x1 Header | RX DET / SCL Dual Function Pin Provision for DS2 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 |
