SIGNAL
DESCRIPTION
DIN33:0
Data bus for the input register. This input register provides a 34 bit, incremental or absolute, phase
value, if the mode pin is low. Alternatively if the mode pin is high, it provides either an 18 bit phase
increment value, via D17:0, and a 16 bit scale value via D33:18 or a 34 bit phase increment value
depending on the JUMP input see below.
SIN15:0
16 bit sine output data in fractional two’s complement format.
COS15:0
16 bit cosine output data in fractional two’s complement format.
CEN
Clock enable for the data input register. When low, data will be latched on the rising edge of the clock.
When high data will be retained in the input register.
MODE
Mode control input. When low, data in the input register is interpreted as either a 34 bit phase increment
value or a 34 bit absolute phase value. When high, the output multipliers are enabled and will scale the
waveforms with the upper 16 bits in the input register. The phase increment is loaded from the the lower
18 bits. The full 34 bit phase increment register can also be loaded using JUMP see below.
JUMP
With MODE low (Frequency or Phase Modulation)
When low JUMP will allow normal phase incrementing to occur. When high, the data on the input pins
will be interpreted as a 34 bit absolute phase value to replace the present value in the accumulator.
JUMP is internally latched to match the delay through the data input register, and to allow data in the
internal pipeline to be correctly processed.
CEN
must also be low to latch the required data from DIN.
When Mode is high (Amplitude Modulation)
When low JUMP will allow normal phase incrementing to occur, with the phase increment value taken
from the lower 18 data inputs. When high, the data on the input pins will replace the full 34 bits of the
phase increment register.
CEN
must also be low to latch the required data.
RES
When high will clear the phase accumulator and phase increment registers, after data in the internal
pipeline has been correctly processed.
CLK
Input clock.
OES
Output enable for SIN 15:0. Outputs are high impedance when
OES
is high.
OEC
Output enable for COS15:0. Outputs are high impedance when
OEC
is high.
VIN
Valid input flag. A delayed version of this input is available on the VOUT pin, with the delay matching
the data processing pipeline delay. This input has no other internal function.
VOUT
Valid output flag. See above.
GND
Five ground pins. All must be connected.
VCC
Four +5V pins. All must be connected.
