HUNLOCK_LINE

_NUM[3:0]

HPLL number/4 of successive err>thresh for hunlock

This register is used by the HPLL. It provides the number of successive lines divided by 4 where the phase

error must be above the required threshold to consider the hlock to be lost. The default value is 8 x 4 lines.

HLOCK_LINE_N

[3:0]

HPLL number/4 of successive err<thresh for hlock

This register is used by the HPLL. Its entry is the number of successive lines divided by 4 where the phase

error must be below the required threshold before the hlock is acquired (a value of 0001 h = 1 means 4

lines). The default value is 2 x 4 lines.

HLOCK_PH_ER_

TH[3:0]

HPLL phase error threshold / 8 for hlock / hunlock

This register provides the phase error threshold for the HPLL. The same value is used for the lock and

unlock mechanism. The entry value is the number of samples multiplied by 8. The default value is 5 x 8

samples.
