FUNCTION
Output swing control:
00 = 300mV_p-p
01 = 600mV_p-p (default)
10 = 600mV_p-p
11 = 900mV_p-p
Input filter bandwidth selection control bit:
1 = Contents of register address 7 bits 3 to 0 are used to select the input filter
bandwidth
0 = Bandwidth of 9.1GHz is used (default)
Input filter bandwidth selection bits:
Register 7 bits 3 to 0 are used to set the input filter bandwidth:
0000 = Maximum bandwidth
1111 = Minimum bandwidth
LOS Assert level control bit:
1 = Contents of register address 11 bits 6 to 0 are used to select the LOS assert
level
0 = LOS Assert level of 50mV_p-p is used (default)
LOS Assert level selection bits:
Register 11 bits 6 to 0 are used to select the LOS assert level:
0000000 = Minimum LOS assert level
1111111 = Maximum LOS assert level
Selected rate setting (read only)
