SNLU300A January 2023 – February 2023 DS160PR1601 , DS320PR1601
2.6 Quick-Start Guide
- Configure the DS320PR1601 to operate in the I2C Primary or Secondary mode by setting the MODE pins to the L1 or L2 level (L1 will first load the EEPROM, then return to I2C Secondary mode, L2 will place the device directly in I2C Secondary mode). This is accomplished by placing a shunt on JMP9 L1 or L2 location.
- Set a unique I2C Secondary address for each channel group by placing shunts in the following arrangement (This will configure the Downstream A channels to 0x18, 0x19, 0x1A and 0x1B, and the Upstream B channels to 0x1C, 0x1D, 0x1E and 0x1F):
- JMP1 1-2
- JMP2 1-2
- JMP3 1-2
- JMP4 5-6
- JMP5 3-4
- JMP6 1-2
- JMP7 1-2
- JMP8 7-8
- Configure JMP20 to either 1-2 or 2-3 to select 3.3 V from system PCIe 3.3 V or on-board regulator.
- Enable all channels by pulling their PWDN pins to GND. This is accomplished by placing a shunt on pins 3-4 on JMP10, JMP11, JMP12, and JMP13.
- Verify that no shunts are placed on JMP22.
- Select the appropriate adapter using JMP17 and connect the USB2ANY or Aardvark Adapter to connector P4 (Note: neither Adapter is supplied with the DS320PR1601EVM-RSC).
- Install SigCon Architect Version 3.0.1.0 (Or latest) application and the DS320PR1601 profile.
Please contact a local FAE for download instructions.
- Plug the EVM into a PCIe x16 server motherboard slot. Ensure the motherboard is powered down before installing the EVM or configured for hot-plug operation.
- Install a compatible PCIe endpoint card into the straddle connector of the EVM.
- Power-up the motherboard.
- Start the SigCon Architect application.
- Select the DS320PR1601 Configuration Page and select the Apply box to enable the device profile. If necessary, edit channel addresses in the Edit Device Addresses box.
- In the DS320PR1601 High Level Page, select Block Diagram as shown in Figure 2-1.
- Select the desired EQ Settings and Driver Flat Gain.
- Select Apply to All Channels to apply the select settings to the select channels.
