PRBS_GEN_

CTRL

CTRL_PRBS_GEN_

CLK_DIVIDER

5:4

R/W

Selects clock divider ratio for when host

selects divided clock to output on PRBS

Generator

(CTRL_PRBS_GEN_SIGNAL_SELECT = 0):

0 = Divide by 2



1 = Divide by 4



2 = Divide by 8



3 = Divide by 16

CTRL_PRBS_GEN_

INVERT

3R/W

Controls optional inversion of the

generated PRBS pattern:

0 = true sense



1 = inverted

CTRL_PRBS_GEN_

DATA_RATE

2:0

R/W

Select PRBS7 data rate when PRBS clock

source not recovered clock

(CTRL_PRBS_GEN_CLK_SRC ≠ 3)

0 = Reserved—do not use

1 = MADI



2 = SD



3 = HD



4 = 3G



5 = Reserved - do not use



6 = Reserved - do not use



7 = Reserved - do not use.

If CTRL_PRBS_GEN_CLK_SRC = 3, then

CTRL_PRBS_GEN_DATA_RATE setting

has no effect and the CDR rate is used

(based on automatic rate detection or

manual rate selection). Additionally, if

the device is locked to an input signal,

only the same rate can be selected for

the PRBS Generator.

RSVD

15:0

R/W

Reserved—do not modify.

EYE_MON_

INT_CFG_0

CFG_EYE_MON_



TIMEOUT_MS

15:0

R/W

CFG_EYE_MON_TIMEOUT[31:16] Most

significant 16 bits of the measurement

time. This is the time spent measuring

bit errors at each point in the eye scan,

i.e. the time to measure one point in the

eye. Units are in microseconds. The Eye

Scanner scans each point twice and

there is some overhead, so the actual

measurement time is twice the number

entered.

Valid range:



1 to 6555d

65536 d to 104895d

131072d to 3350000d
