Direct Digital Synthesizer
The 14-bit HSP45314 provides a complete Direct Digital
Synthesizer (DDS) system in a single 48-pin LQFP package.
A 48-bit Programmable Carrier NCO (numerically controlled
oscillator) and a high speed 14-bit DAC (digital to analog
converter) are integrated into a stand alone DDS.
The DDS accepts 48-bit center and offset frequency control
information via a parallel processor interface. Modulation
control is provided by 3 external pins. The PH0 and PH1 pins
select phase offsets of 0, 90, 180 and 270 degrees, while the
ENOFR pin enables or zeros the offset frequency word to
the phase accumulator.
The parallel processor interface has an 8-bit write-only data
input C(7:0), a 4-bit address A(3:0) bus, a Write Strobe
(WR), and a Write Enable (WE). The processor can update
all registers simultaneously by loading a set of master
registers, then transfer all master registers to the slave
registers by asserting the UPDATE pin.
