O

PERATIONS

 

After it is confirmed that the board is communicating with the PC, click on the 

OpenDialog.txt

 button, which will 

open the GUI Interface (as shown below) where you will be able to control the device.  

The LED indicators on the board turn on (

RED

) when no Analog signal or a Run Length Limit (RLL) or K28.5 

characters are detected. RX/TX ASD = Analog Signal Detect and RX/TX SDU = RLL or K28.5 detect. 

 

 

 

 

 

 

 

 

 

 

CMU LOL: 

Green

 LED = CMU is 

Locked with REFCLK. 

Red

 LED = CMU not 

Locked with REFCLK 

Red

 LED = RX/TX analog signal not 

detected & RLL & K28.5 errors occurred.

Green

 LED = RX/TX analog signal 

detected and it is RLL & K28.5 free.

Pattern 
Checker

Pattern Generator:

Can only be used in 
Retimer Mode. 

Supports: 

a) 2^7, 2^23 & 2^31 
PRBS patterns. 
 b) CRPAT, CJPAT & 
CSPAT FC patterns. 
c) User defined 40- & 
64- bit user patterns. 

 

Update:

 

For status 
registers that 
clear only on 
read, it is 
necessary to 
click on 
“Update” more 
than once.  

Reset:

 

Resets 

device.

   

16 Different Mode Selections:

Please refer to Table 3 in the 
VSC8228 data sheet for pin control 
mode selections or simply choose a 
mode in the drop down

 

menu.

 

RXCLK Output: 
J11 & J12 

RX/TX 
ADU/SDU: 

Green 

LED = 

Analog signal 
detected & no 
RLL or K28.5 
detected. 
Vice versa for 

Red

 LED.  

Rx/Tx Retimer or Repeater Mode: 

Using Pin Control TXP/RXP High = 
Repeater Mode and Low = Retimer Mode 

RX/TX Data 
CTRL: 

Using Pin Control 
TXOEN/RXOEN 
High = Enable 
RX/TX data 
output 

CMU Rate Control: 

(Please refer to Tables 5 & 6 in the VSC8228 data 

sheet for REFCLK rates and data rate selection for Pin Control, or use the drop 
down menu).  

 

Supports: 

a) 1/2/4Gb/s Fibre Channel with 106.25MHz or 125MHz REFCLK. 
b) 1/2/4Gb/s Ethernet with 125MHz or 62.5MHz REFCLK. 
c) OC-3/12/48 SONET and ESCON with 62.5MHz, 125MHz & 155.52MHz 
REFCLK.

   

 

RX/TX Input Signal Equalization:

 

By default or if the device is reset, the RX/TX 
input equalization will be set to 7.0dB.
