For lower data rates with higher insertion loss, you can use higher values.

•

The typical values for RF_B0 and RF_B1 are 1 and 4. For high data rates (50 Gbps

and above) and for longer channels (20 dB and above), you can use a RF_B1

value of 6 or 8 (max) to take advantage of full EQ capabilities. Depending on the

system and temperature ramp, you may be required to use a RF_B0 setting of 2

to allow sufficient room on both up and down ramps.

•

Sweep the RF_B0/RF_B1 values and apply optimized values for a channel or group

(short/medium/long) of channels whenever possible.

•

During continuous adaptation, fixing LF_Max (which limits the LF adaptation

range) and adapting RF_B0 provides the best performance over temperature

ramp.

3.1.4. Loopback modes

Loopback modes are DFT features used to verify different blocks of the transceiver

PMA.

Intel Stratix 10 E-Tile transceivers have loopback modes to debug different blocks of

the transceiver. Intel Stratix 10 E-Tile transceivers support the following loopback

modes:
•

Internal or serial loopback

•

Reverse parallel loopback

3.1.4.1. Internal or Serial Loopback Path

The internal or serial loopback path sets the CDR to recover data from the serializer

instead of the receiver serial input pin.

The transmitter buffer sends data normally, but internal or serial loopback takes the

data before the buffer.

It is implemented completely on-chip and does not require any connector on the serial

path. This loopback path is enabled independently of the TX buffer enablement.

The Intel Stratix 10 E-Tile transceiver channel also supports external loopback where

you have to connect the TX differential outputs to the RX differential inputs. This

external connection must consist of a transmission path with 100 Ω differential mode

impedance.
