2.6 Quick-Start Guide (Pin Mode)

Check that the shunts are at the following positions as shown below:
1. The redriver is configured to operate in Pin Mode (MODE pin tied to L0 using J23 header).
2. RX_Detect state machine is enabled by leaving J17 No Connect (Redriver Channel Tx must detect 

termination to enable the channel).

3. The redriver is enabled (PD0 and PD1 pins tied to GND using J25 and J26 headers).
4. EQ level of the RX CTLE of the redrivers is set by using J19 - J22.Gain is set by headers J18 and J24. 

Please refer to datasheet for CTLE and GAIN values.

2.7 Quick-Start Guide (SMBus Slave Mode)

1. Configure all devices to operate in the SMBus Secondary Mode by setting the MODE pin to the L2 level. 

This is accomplished by placing a shunt on J23 - L2 location.

2. Set a unique SMBus Secondary address by placing shunts on J19 (ADDR0) and J20 (ADDR1). Refer to 

Table 2-3

 for details.

3. Move shunts on J17 and J18 to pins 9-10 to connect SCL and SDA.
4. Select I2C controller (Aardvark or USB2ANY) by placing shunts on JMP1.
5. Connect the 

USB2ANY

 (Or aardvark) Adapter to P3 (Note that the Adapter is not supplied with the 

DS160PR810-SMP-EVM).

6. Install 

SigCon Architect

 Version 3.0.1.0 application and the DS320PRxx profile.

7. Power-up the EVM board (P1=3.3V, P2=GND).
8. Start the SigCon Architect application.
9. Select the DS320PR8xx Configuration Page and click on "Apply" box to enable the device profile. If 

necessary, edit devices addresses in the Edit Device Addresses box.

10. In the DS320PR8xx High Level Page, select Block Diagram as shown in 

Figure 2-1

.

11. Select the desired EQ Settings and Driver VOD.
12. Select channels to which you want to apply the selected settings and click "Apply to All Channels".
