BIT
TYPE
NAME
DESCRIPTION
0 LSB
R/W
RES_PACKED
Puts the resampler serial inputs into the 32 bit transfer mode where each
complex pair is packed into 32 bit words. The complex pair is formatted as I word
in the upper 16 bits and the Q word in the lower 16 bits. Each word is formatted
as MSB first.
1
R/W
SC_MODE
Set to zero when the serial controller is being used with the resampler and is set
to 1 when it is used with the channels.
2
R/W
RCK_POL
The
RIN
Input bits and
RFS
frame strobes are clocked in on the trailing edge of
RSCK when this bit is set. The rising edge is used when this bit is low.
3
R/W
RFS_POL
The
RFS
signal is treated as active low when this bit is set. Otherwise the signal
is treated as active high.
4
R/W
RES_PARALLEL_A
The parallel/Serial control for resampler input A. When low input for resampler
channel A is taken from the serial port. When high it is taken from the resampler
input page registers.
5
R/W
RES_PARALLEL_B
The parallel/Serial control for resampler channel B.
6
R/W
RES_PARALLEL_C
The parallel/Serial control for resampler channel C.
7
R/W
RES_PARALLEL_D
The parallel/Serial control for resampler channel D.
BIT
TYPE
NAME
DESCRIPTION
0-3 LSB
R/W
ROCK_RATE
The resampler serial output clock rate is ROCK = CK/(1+ROCK_RATE). The
serial clock changes on the rising edge of CK when ROCK_RATE is even.
4
R/W
ROCK_POL
Resampler serial output clock polarity. Inverts ROCK. When ROCK_POL=0 and
ROCK_RATE=0, ROCK is a slightly delayed version of CK.
5
R/W
ROFS_POL
Resampler frame strobe polarity. If low, the frame strobe pulses high for one
RCK period prior to the first transmitted bit. If high the frame strobe pulses low.
6,7
R/W
ROCK_SYNC
Sync control for the resampler output clock. The sync settings are 0 =never; 1 =
SIA; 2 =SIB; 3=Always.
BIT
TYPE
NAME
DESCRIPTION
0-2 LSB
R/W
SUM_ROUND
Round the output to 22-(2*SUM_ROUND) bits. The remaining low order bits are
cleared. In normal use SUM_ROUND is 0 for all chips in a sum path except the
final one. The final one is programmed to match the number of bits used by the
D/A or other follow-on devices.
3-5
R/W
SUM_SCALE
Shift the sum output up by SUM_SCALE bits prior to rounding. In normal use
SUM_SCALE is 0 for all chips in a sum path except the final one. The final one is
typically programmed so that the output has a 14 dB crest factor.
6
R/W
SUM_DELAY
The latency sumin to sumout is 8 cycles. Enabling this bit adds 8 cycles of
latency to the output of the 4 internal channels to match the delay from one
previous chip.
7
R/W
SUM_CLEAR
Clears sumin data so that regardless of the input to the sumin port it does not
affect the sum output.
