identified by the data type that it follows, SEROUTB can only
be fully independent of the sequence in SEROUTA if it does
not use any of the same data word types. This implies a
partition as described in Example 1. Once a data word that is
used in SEROUTA is called out in SEROUTB, the remaining
sequence in SEROUTB will be identical to that portion of
SEROUTA sequence that follows the duplicate data type.
This follows from using the “Link follows ‘data type’ data”
for word linkage.
NOTE: Each type of data word should be used only once in each
data stream. If the “Link following I data” is programmed
with the data type identifier for I , then the part will repeat the
I data word until all of the data word locations are filled. In
Example 1, if bits 20-18 were erroneously programmed to
000 (I data) then the SEROUTA would be four sequential
repeats of the I data word.
Serial Output Configuration Example 2:
It is desired to output only three data words on each serial
output. 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.

As shown by this example, once Q was linked to |r| in the
SEROUTA chain, the SEROUTB chain must have |r|
following Q, if Q is selected. Figure 35 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
created using Control Word 19. Figure 36 shows the four
possible 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.
