Serial Output Configuration Example 2:
It is desired to output only three data words on each serial out-
put. The I data word, followed by the Q data word, followed by
the Magnitude data word is to be output on SEROUTA. The Q
data word followed by the Magnitude data word, followed by
the one other data word to be output on SEROUTB. The
choices for the remaining data word in the SEROUTB signal
are: phase, frequency, AGC level and timing error. Table 15
illustrates how Control Word 19 should be programmed.
The serial data stream looks like:
As shown by this example, once Q was linked to |r| in the
SEROUTA chain, the SEROUTB chain must have |r| follow-
ing Q, if Q is selected. Figure 32 illustrates the construction
of the serial output streams. If the serial data stream was
changed to be a length of four data words, then, by default,
the SEROUTA would be whatever is selected for SEROUTB
data word 3. SEROUTB would need to identify the fourth
data word.
Thus, SEROUTA and SEROUTB are not fully
independent because they share the Q data word
(and by
default, the MAGNITUDE follows Q data link and whatever is
selected for data word 3 to follow MAGNITUDE data in
SEROUTB).
The other signals provided with the SEROUTA and
SEROUTB are the SERSYNC and the SERCLK. The
SERSYNC signal can be programmed in either early or late
sync mode. The sync signal is pulsed active low or active
high for each information word link of the chain of data cre-
ated using control word 19. Figure 33 shows the four possi-
ble configurations of SERSYNC as programmed using
Control word 20.
As previously discussed, Control Word 20, bits 17 and 19,
set the functionality of the LSB of each data word. These bits
may be programmed to be either a logic “0”, logic “1” or as
normal data. The fixed states are designed to allow the
microprocessor to synchronize to the serial data stream.
