6. Control Input Pin Read Timing (Pins CL.ED.SEL, CORR.SEL and D.S.CONTROL)
CL.ED.SEL
The LC7074/M reads in the state of the CL.ED.SEL pin about 1 ms after a reset clear. It uses this signal for the
internal settings that determine the clock output polarity.
CL. ED. SEL Pin Read-In Timing
CORR.SEL and D.S.CONTROL
The LC7074/M continuously checks the state of these pins. As a result, error correction can be turned on or off and
the DATA START signal output form can be changed at any time.
– During synchronization detection (synchronization sequence)
The pin states are read-in on each bit of demodulated data from the RDS demodulation IC (at the points shown by
arrows in the figure). The state is read into the IC if the input values agree four times in a row.
