FREQUENCY REGISTER
The three bytes together constitute a 24-bit frequency
control word to represent the sound carrier (i.e. mixer)
frequency in accordance with the following formula:
f
f
clk
where:
data = 24-bit frequency control word
f
mix
= desired sound carrier frequency
f
clk
= 12.288 MHz (clock frequency of mixer)
2
24
= 16777216 (number of steps in a 24-bit word size).
Example: A 5.5 MHz sound carrier frequency will be
generated by sending the following sequence of data
bytes to the TDA9875A (data = 7509333 in decimal
notation or 72555 in hexadecimal):
01110010 10010101 01010101.
As three bytes are required to define a carrier frequency,
execution of this command starts only after all bytes have
been received. If an error occurs, e.g. a premature STOP
condition, partial data for this function is ignored.
The default setting at power-up is 0000 0000 for all three
bytes.
Most significant part at subaddress 3 and least significant
part at subaddress 5 (see Table 20).
