Functional Description
(Continued)
Figure 4 shows the input data format. A start bit of logical
‘‘1’’ precedes the 32 bits of data. At the 36th clock a LOAD
signal is generated synchronously with the high state of the
clock, which loads the 32 bits of the shift registers into the
latches. At the low state of the clock a RESET signal is
generated which clears all the shift registers for the next set
of data. The shift registers are static master-slave configura-
tion. There is no clear for the master portion of the first shift
register, thus allowing continuous operation.
If the clock is not continuous, there must be a complete set
of 36 clocks otherwise the shift registers will not clear.
Figure 2a shows the pin-out of the MM5452. Bit 1 is the first
bit following the start bit and it will appear on pin 18.
Figure 3 shows the timing relationships between data, clock
and DATA ENABLE.
