Address: 5AH
Type: Read / Write
Default Value: 10000101
Bit
Name
Description
7
COARSE_PH_LOS_LIMT_EN
This bit controls whether the occurrence of the coarse phase loss will result in the T0/T4 DPLL unlocked.
0: Disabled.
1: Enabled. (default)
6
WIDE_EN
Refer to the description of the MULTI_PH_8K_4K_2K_EN bit (b4, 5AH).
5
MULTI_PH_APP
This bit determines whether the PFD output of T0/T4 DPLL is limited to ±1 UI or is limited to the coarse phase limit.
0: Limited to ±1 UI. (default)
1: Limited to the coarse phase limit. When the selected input clock is of 2 kHz, 4 kHz or 8 kHz, the coarse phase limit depends
on the MULTI_PH_8K_4K_2K_EN bit, the WIDE_EN bit and the PH_LOS_COARSE_LIMT[3:0] bits; when the selected input
clock is of other frequencies but 2 kHz, 4 kHz and 8 kHz, the coarse phase limit depends on the WIDE_EN bit and the
PH_LOS_COARSE_LIMT[3:0] bits. Refer to the description of the MULTI_PH_8K_4K_2K_EN bit (b4, 5AH) for details.
4
MULTI_PH_8K_4K_2K_EN
This bit, together with the WIDE_EN bit (b6, 5AH) and the PH_LOS_COARSE_LIMT[3:0] bits (b3~0, 5AH), determines the
coarse phase limit when the selected input clock is of 2 kHz, 4 kHz or 8 kHz. When the selected input clock is of other frequen-
cies but 2 kHz, 4 kHz and 8 kHz, the coarse phase limit depends on the WIDE_EN bit and the PH_LOS_COARSE_LIMT[3:0]
bits.
3 - 0 PH_LOS_COARSE_LIMT[3:0]
These bit set the coarse phase limit. The limit is used only in some cases. Refer to the description of the
MULTI_PH_8K_4K_2K_EN bit (b4, 5AH).
0000: ±1 UI.
0001: ±3 UI.
0010: ±7 UI.
0011: ±15 UI.
0100: ±31 UI.
0101: ±63 UI. (default)
0110: ±127 UI.
0111: ±255 UI.
1000: ±511 UI.
1001: ±1023 UI (T0); Reserved (T4).
1010-1111: Reserved.
