DESCRIPTION

tst_sel_slice

1C00

(TESTING PURPOSES) This selects the

slice block that is generating the tst_out

data. (which DUC/DDC)

tst_rate

1C00

The value here controls the output clock

rate on the clk_tst pin. A value of 0 gives

a full-rate output clock (txclk rate), a 1

gives half-rate output clock, a 3 gives

1/4th rate output clock, and so on. The

number of txclk cycles for which the

clk_tst signal is high + low = 1 + tst_rate.

interf_round

1C00

Controls round point on the transmit

output data; {00 = 18b, 01=16b, 10=14b,

11=12b}. Rounded output data is MSB

justified. For example, a 12b round point

causes the output data to be presented

on the output pins (17:6), and the output

pins (5:0) to be held low.

interf_ena

1C00

Enables the individual transmit output

busses 3 through 0. Disabled busses are

always held low.

interf_interl

1C00

Enables interleaved I/Q data when

asserted.

interf_real

1C00

Enables real only outputs when asserted.

Complex data is output when cleared.

interf_scale_3

1C00

Selects the scaling between the

sumchain output signals and the transmit

output pins and transmit composite

power meters. Appropriate limiting and

rounding is performed as required by the

programmed round point. Gain =

2(interf_scale). For sumchain 3.

interf_scale_2

1C00

Selects the scaling between the

sumchain output signals and the transmit

output pins and transmit composite

power meters. Appropriate limiting and

rounding is performed as required by the

programmed round point. Gain =

2(interf_scale). For sumchain 2

interf_scale_1

1C00

Selects the scaling between the

sumchain output signals and the transmit

output pins and transmit composite

power meters. Appropriate limiting and

rounding is performed as required by the

programmed round point. Gain =

2(interf_scale). For sumchain 1

interf_scale_0

1C00

Selects the scaling between the

sumchain output signals and the transmit

output pins and transmit composite

power meters. Appropriate limiting and

rounding is performed as required by the

programmed round point. Gain =

2(interf_scale). For sumchain 0
