8.2.4.1. Transceiver Toolkit Parameter Settings

Table 177.  Parameter Settings in the Channel Parameters Pane
Parameter Description Control Pane
Bit error rate (BER) Reports the number of errors divided by bits tested since the last reset of the checker. Receiver pane
Channel address Logical address number of the transceiver channel. Transmitter pane and Receiver pane
CTLE AC Gain Specifies the receiver's continuous time linear equalization (CTLE) AC gain. Receiver pane
CTLE EQ Gain Specifies the CTLE EQ Gain for the receiver. Receiver pane
Number of bits tested Specifies the number of bits tested since the last reset of the checker. Receiver pane
Number of error bits Specifies the number of error bits encountered since the last reset of the checker. Receiver pane
Pre-emphasis settings This programmable module boosts high frequency components in the transmit data for each transmit buffer signal. This action counteracts possible attenuation in the transmission media. The setting consists of two parameters which are Pre-emphasis 1st post-tab and Pre-emphasis 1st pre-tab. Transmitter pane
Receiver channel Specifies the name of the selected receiver channel. Receiver pane
Refresh After loading the .sof file, loads fresh settings from the registers after running dynamic reconfiguration. Transmitter pane and Receiver pane
Reset Resets the current test. Receiver pane
Locked to ref Shows the receiver status in lock-to-reference (LTR) mode. Receiver pane
Locked to data Shows the receiver status in lock-to-data (LTD) mode. Receiver pane
Combined Adaptation mode Select one of the adaptive modes based on your system loss characteristics if you intend to use the adaptation engine in the RX PMA. Receiver pane
Loopback Mode Inserts a serial loopback before the buffers, allowing you to form a link on a transmitter and receiver pair on the same physical channel of the device. The PMA support three serial loopback modes: serial loopback, reverse serial loopback pre-CDR, reverse serial loopback post-CDR. Receiver pane
Start Starts the pattern generator or checker on the channel to verify incoming data. Transmitter pane and Receiver pane
Stop Stops generating patterns and testing the channel. Transmitter pane and Receiver pane
PRBS pattern

PRBS pattern is a test pattern sent by the transmitter channel.

Test patterns available are: PRBS7, PRBS9, PRBS15, PRBS23, and PRBS31.

Transmitter pane and Receiver pane
Invert Polarity Setting to invert the polarity of the TX or RX channel serial data or both. Transmitter pane and Receiver pane
Transmitter channel Specifies the name of the selected transmitter channel. Transmitter pane
VGA DC Gain The variable gain amplifier (VGA) amplifies the signal amplitude and ensures a constant voltage swing before the data enters the clock data recovery (CDR) block for sampling Receiver pane
VOD Programmable transmitter differential output voltage. Transmitter pane
