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.
