Adata signal is composed of 16bits. Eleven bits
areassigned for frequency data and the remain-
ing 5bits are assigned for the receptionbands.
Receiving frequency data input control timing
input terminal.
Eachtime adata signal is sent, atiming signal is
concurrently sent from pins 20 and
21
of IC7 to
this terminal, to read the data signal.
Two lines
(CK-1
and CK-2) are used for timing
the data signal reading. They havethe following
timing relationship with the data signal.
