Serial Direct Output Port Mode
The Serial Direct Output Port Mode offers the ability to
construct two serial output data streams, SEROUTA AND
SEROUTB, from 16-bit I, Q, magnitude, phase, frequency,
timing error, and AGC level data words. The total number of
data words (1 to 8) for serial output, and the sequential order of
these data word components of the serial output are
programmable. Each data word may be used once in either the
SEROUTA or SEROUTB data streams. Figure 34 illustrates the
conceptual implementation of the Serial Direct Output Port
Mode.
In the Serial Direct Mode, the output data is loaded into
Serial Shift Registers and routed to two serial output pins,
SEROUTA and SEROUTB. The serial output shift clock,
SERCLK, is PROCCLK divided by 1, 2, 4, 8, or 16. The
divide down ratio is programmed using Control Word 20,
Bits 14-16. The data is shifted out on the rising edge of the
internal SERCLK . The external clock polarity of SERCLK is
programmable via Control Word 20, Bit 18. A sync signal is
process for identifying the next word is to select a three bit
data type identifier which represents the data type to follow
the source data type. Program these bits into the Control
Word 19 field representing the “Link following X data”,
where X = the source data type, defines the second word in
the sequence. Likewise, the third data word is linked by
selecting the Control Word 19-bits that identify the “Link
following X data”, where X = the data type of the second
word in the serial chain. The process continues until all the
desired data words have been linked.
NOTE: I and Q are sample aligned in time. |r| and φ are sample
aligned in time, but one sample delayed from I or Q. The
frequency sample is delayed in time from I or Q by 1
sample time + 63 tap FIR impulse response. If the FIR is
set to decimate, the FIR output will be repeated every
sample time until a new value appears at the filter output.
(i.e., the frequency samples are clocked out at the I, Q
sample rate regardless of decimation.)
TABLE 13. LINKING CONTROL WORDS FOR SERIAL OUTPUT
DATA TYPE
provided for detection of the start or end of each word in
the serial sequence. Control Word 20, Bit 17, sets the
SERSYNC signal location as either preceding the MSB
(typical for interfacing with microprocessors) or following
the LSB (typical for interfacing to D/A converters). Control
Word 20, Bit 19, sets the SERSYNC polarity as active low
or high. The LSB of each data word can be configured as
either the true LSB data, or set at a fixed logic “1” or “0” for
use as a tag bit. Control Word 20, Bits 0-13 set the LSB of
each of the 7 types of data words that can be configured in
the serial output stream. Control Word 19, Bits 21-24 set
the number of serial data words that will be linked to form
the serial outputs. Up to 7 data words can be linked to form

the serial output. SEROUTA and SEROUTB will have an
identical number of words in the serial output streams.
The 16-bit I, Q, magnitude, phase, frequency, timing error,
Two examples will illustrate the process of configuring a serial
output using the Serial Output mode.
The serial data stream looks like:
AGC level, and “zeros” data words are loaded into their
respective shift registers. The Magnitude and AGC Level
data word are unsigned binary format with a leading zero,
while the remaining signals are 2’s complement format.
Any of the eight data sources can be selected as the first
serial word for SEROUTA or SEROUTB. Control Word 19,
Bits 25-30 set the data type for the first serial word for
SEROUTA and SEROUTB. The three bit data type
identifier is shown both in Table 13 and in Figure 34, to the
right of the controls for the cross matrix switch. Serial
output data word sequences are formed by linking data
words by programming the data source for each shift
requester ’s shift input signal. This programming links the
Shift Registers together in one or two serial chains. Thus,
the Control Word 19 term “Link follows X data”, where X is
one of the seven data types. Once the data source data
word is selected (by programming a three bit word
representing one of the data types into Control Word 19,
Bits 25-27 (SEROUTA), and 28-30 (SEROUTB)), the
