Base clock
10.667 MHz/4 =
2.667 MHz
2.667 MHz x (38/55) =
1.8424 MHz (Average)
Average transfer rate is 115.152 kbps φ =
10.667
Average transfer rate = 1.8424 MHz/16 = 115.152 kbps Average error = −0.043%
1 bit = Base clock x 8

5.333 MHz x (38/55) =
3.6848 MHz (Average)
Average transfer rate is 460.606 kbps
Average transfer rate = 3.6848 MHz/8 = 460.606 kbps Average error = −0.043%
Note: * The 1-bit length changes according to the base clock synchronization.
