(3) Explanation of the serial data
· It is the data which sets the program counter number of the dividing.
This data can set a transmission frequency.
· It is a binary value. It sets D
11
With MSB and it sets D
0
with LSB.
· It controls EVR. L-ch and R-ch are set at the same time.
Example
In case of 99.7MHz oscillation
99.7MHz÷100kHz(fref)=997→3E5(HEX)
