Pin Description
NAME
TYPE
DESCRIPTION
V
CC
+5V power supply pin.
GND
Ground
P0-1
I
Phase modulation inputs (become active after a pipeline delay of four clocks). A phase shift of 0, 90,
180, or 270 degrees can be selected as shown in Table 1.
CLK
I
NCO clock. (CMOS level)
SCLK
I
This pin clocks the frequency control shift register.
SEL_L/M
I
A high on this input selects the least significant 32 bits of the 64-bit frequency register as the input to
the phase accumulator; a low selects the most significant 32 bits.
SFTEN
I
The active low input enables the shifting of the frequency register.
MSB/LSB
I
This input selects the shift direction of the frequency register. A low on this input shifts in the data LSB
first; a high shifts in the data MSB first.
ENPHAC
I
This pin, when low, enables the clocking of the Phase Accumulator. This input has a pipeline delay of
four clocks.
SD
I
Data on this pin is shifted into the frequency register by the rising edge of SCLK when SFTEN is low.
TXFR
I
This active low input is clocked onto the chip by CLK and becomes active after a pipeline delay of four
clocks. When low, the frequency control word selected by SEL_L/M is transferred from the frequency
register to the phase accumulator’s input register.
LOAD
I
This input becomes active after a pipeline delay of five clocks. When low, the feedback in the phase
accumulator is zeroed.
OUT0-11
O
Output data. OUT0 is LSB. Unsigned.
All inputs are TTL level, with the exception of CLK.
Overline designates active low signals.
