78 / 112 page ![]() Register List STV2310 78/112 DDECCONT28 Register Description DDECCONT29 Register Description DDECCONT2A Register Description Address (hex): 28h Reset Value (bin): 1000 0010 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 HUNLOCK_LINE_NUM[3:0] HLOCK_LINE_NUM[3:0] Bit Name Function 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 UM [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. Address (hex): 29h Reset Value (bin): 0101 0101 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 HLOCK_PH_ER_TH[3:0] Bit Name Function Bit 7 Reserved. Must be set to 0. Bit 7 Reserved. Must be set to 1. Bits [5:4] Reserved. Must be set to 01. 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. Address (hex): 2Ah Reset Value (bin): 1000 0010 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 CLAMP_PROP[1:0] CLAMP_DER[1:0] CLAMP_INT[2:0] |
