CONTROL WORD 19: SERIAL OUTPUT ORDER (SYNCHRONIZED TO PROCCLK)
Reserved.
The Resampler NCO output is divided down by the value loaded into this register plus 1. Load
with a value that is one less than the desired period. Bit 27 is the MSB.
The reference clock is divided down by the value loaded into this register plus 1. Load with a
value that is one less than the desired period. Bit 27 is the MSB. A minimum preload of “I” is
required.
Reserved.
Serial Output A source. The serial data source is selected using Table 12 (see Output Section).
Serial Output B source. The serial data source is selected using Table 12 (see Output Section).
This parameter determines the number of SERSYNC pulses generated. It can be set from 1 to
7. If this parameter matches the number of serial words that are linked together to form a serial
output chain, then there will be a sync pulse for every word in the serial output. In applications
where a processor is receiving the serial data, it may be desirable to have a single SERSYNC
pulse for the whole serial output chain, instead of a SERSYNC for each word in the data chain.
The processor then parses out the various data words. As an example, if the I and Q are
chained together and a single SERSYNC pulse is generated for this serial output chain, no am-
biguity exists in the processor about which two data samples (one from I and one from Q) are
related.
The serial data word, or link, following the I data word is selected using Table 12
(see Output Section).
The serial data word, or link, following the Q data word is selected using Table 12
(see Output Section).
The serial data word, or link, following the MAG data word is selected using Table 12
(see Output Section).
The serial data word, or link, following the PHAS data word is selected using Table 12
(see Output Section).
The serial data word, or link, following the FREQ data word is selected using Table 12
(see Output Section).
The serial data word, or link, following the AGC data word is selected using Table 12
(see Output Section).
The serial data word, or link, following the TIMERR data word is selected using Table 12
(see Output Section).
