User Guide

PMA Setting—Only available for the XCVR test. This control allows you to make

changes to the PMA parameters that affect the active transceiver interface. The

following settings are available for analysis:

■ Serial Loopback—Routes the selected TX output signal back to the RX input

signal on-chip to verify operation without using an external loopback board.

■ VOD—Specifies the voltage output differential of the transmitter buffer.

■ Pre-emphasis tap

Pre—Not available.

First post—Specifies the amount of pre-emphasis on the first post tap of the

transmitter buffer.

Second post—Not available.

■ Equalizer—Specifies the setting for the receiver equalizer.

■ DC gain—Specifies the DC portion of the receiver equalizer.

Data Type—Specifies the type of data contained in the transactions. The following

data types are available for analysis:

■ PRBS7—Pseudo-random 7-bit sequences

■ PRBS15—Pseudo-random 15-bit sequences

■ PRBS23—Pseudo-random 23-bit sequences

■ PRBS31—Pseudo-random 31-bit sequences

■ HF—Highest frequency divide-by-4 data pattern

10101010

■ LF —Lowest frequency divide-by-4 data pattern

11110000
