6.2 SQI Mapping with Link Quality

The following table maps the read value of Register 0x198[7:0] (SQI 8-bit) with OA specified 3-bit SQI value and link quality.

Table 6-1 SQI Mapping from 8-bit to 3-bit
SQI 8-bit SQI 3-bit Link Quality
SQI < 0x28 0 *No link
0x28 ≤ SQI < 0x31 1 Bad
0x31 ≤ SQI < 0x3B 2
0x3B ≤ SQI < 0x44 3
0x44 ≤ SQI < 0x4B 4
0x4B ≤ SQI < 0x58 5 Good
0x58 ≤ SQI < 0x64 6 Excellent
0x64 ≤ SQI 7
