2.10 Quick-Start Guide (Pin Mode)
Check that the shunts are at the following positions as shown in
:
1. The redrivers are configured to operate in Pin Mode (MODE pins tied to L0 using J1 header).
2. RX_Detect state machine of all redrivers is enabled by leaving J2 open.
3. The redrivers are enabled (PWDN pins tied to GND using J4 header). Alternatively, for PCIe applications,
the PWDN pins may be driven by PCIe Present (PRSNT) signal by leaving J4 open and placing a shunt
across pins 1 and 2 of J6.
4. The board is configured for any PCIe bus width (PRSNT signal controls set as shown in
using J7,
J8, J9 and J10 headers).
5. DC Gain of all redrivers is set to 0 dB by leaving J14 open for the downstream redrivers and by leaving J21
open for the upstream redrivers.
6. EQ level of the RX CTLEs of all redrivers is set to 10 dB at 16 GHz by using J15 and J16 for the downstream
redrivers and J22 and J23 for the upstream redrivers.
7. If necessary, adjust EQ levels of the downstream redrivers, or upstream redrivers, or both, by arranging
shunts on J15 and J16 for downstream redrivers and J22 and J23 for the upstream redrivers.
8. 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.
9. Install a compatible PCIe endpoint card into the straddle connector of the EVM.
10. Power-up the motherboard.
2.11 Quick-Start Guide (SMBus Slave Mode)
1. Configure all devices to operate in the SMBus Slave Mode by setting their MODE pins to the L2 level. This is
accomplished by placing a shunt on J1 L2 location.
2. Set a unique SMBus Slave address for each device by placing shunts in the following arrangement:
• On J15 connector, place shunts in L0 locations for all downstream devices (DS1_0 and DS2_0; DS1_1
and DS2_1 are a Don't Care).
• On J16 connector, place shunts in L0 locations for the DS1_0 and in L1 locations for DS2_0 (DS1_1 and
DS2_1 are a Don't Care).
• On J22 connector, place shunts in L0 locations for all upstream devices (US1_0 and US2_0; DS1_1 and
DS2_1 are a Don't Care).
• On J23 connector, place a shunt in L2 location for the US1_0 and remove shunts for US2_0 to achieve
L3 level (US1_1 and US2_1 are a Don't Care).
3. Move shunts from pins 1-2 to pins 2-3 on J17, J18, J19, J20, J24, J25, J26, and J27 to connect the dual
function redriver pins to the SMBus, I2C bus.
4. Enable all devices by pulling their PWDN pins to GND. This is accomplished by placing a shunt on J4
between PWDN and GND.
5. Connect the
Adapter to J3 (Note that the USB2ANY Adapter is not supplied with the
DS320PR810-RSC-EVM).
6. Install
Version 3.0.0.15 application and the DS320PR810 profile.
7. 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.
8. Install a compatible PCIe endpoint card into the straddle connector of the EVM.
9. Power-up the motherboard.
10. Start the SigCon Architect application.
11. Select the DS320PR810 Configuration Page and click
Apply
box to enable the device profile. If necessary,
edit devices addresses in the Edit Device Addresses box.
12. In the DS320PR810 High Level Page, select Block Diagram as shown in
.
13. Select the desired EQ Settings and Driver VOD.
14. Select devices you want to apply the selected settings and click
Apply to All Channels
.
