10.3.4.68 ATPL360_REG_SYNC_XCORR_THRESHOLD (0x403C)
Correlation thresholds for synchronization (preamble detection). The format of each threshold is uQ0.16. It represents percentage with respect to the maximum ideal value of correlation (computed internally in PL360).
Access: Read-write.
Value Range: 12 bytes (see Table 10-39).
Default value: See Table 10-40.
Byte 0-1 | Byte 2-3 | Byte 4-5 | Byte 6-7 | Byte 8-9 | Byte 10-11 |
---|---|---|---|---|---|
SYNC_TH_A | SYNC_TH_B | SYNC_2_3_TH_A | SYNC_2_3_TH_B | SYNC_1_2_TH_A | SYNC_1_2_TH_B |
where:
- SYNC_TH_A: Threshold for detection of complete TYPE_A preamble. Used for frame synchronization.
- SYNC_TH_B: Threshold for detection of complete TYPE_B preamble. Used for frame synchronization.
- SYNC_TH_2_3_A: Threshold for detection of 2/3 TYPE_A preamble. Used to lock AGC.
- SYNC_TH_2_3_B: Threshold for detection of 2/3 TYPE_B preamble. Used to lock AGC.
- SYNC_TH_1_2_A: Threshold for detection of 1/2 TYPE_A preamble. Used to activate carrier detect.
- SYNC_TH_1_2_B: Threshold for detection of 1/2 TYPE_B preamble. Used to activate carrier detect.
