2.9 DS320PR410-RSC-EVM Upstream Devices Control

Table 3-9 shows DS320PR410-RSC-EVM upstream devices controls that affect US1, US2, US3, and US4 devices on the board.

Table 2-9 EVM Upstream Devices Controls
COMPONENT NAME FUNCTION / DESCRIPTION
J26 4x2 Header Gain Controls tied to GAIN pins of all downstream device banks (GAIN_US)
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)
J27 17x2

Pin Mode (Default): EQ1 controls for each downstream device and device bank.

Use pins 1–8 for configuring EQ1 pin of US1 device.

Use pins 9–16 for configuring EQ1 pin of US2 device.

Use pins 17–24 for configuring EQ1 pin of US3 device.

Use pins 25–32 for configuring EQ1 pin of US4 device.

SMBus, I2C Modes: ADDR1 controls for each downstream device.

Use pins 1–8 for configuring ADDR1 pin of US1 device.

Use pins 9–16 for configuring ADDR1 pin of US2 device.

Use pins 17–24 for configuring ADDR1 pin of US3 device.
