Direct Digital Synthesizer
The 14-bit ISL5314 provides a complete Direct Digital
Synthesizer (DDS) system in a single 48 Ld 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. A 40-bit
frequency tuning word can also be loaded via an asynchronous
serial interface. Modulation control is provided by 3 external
pins. The PH0 and PH1 pins select phase offsets of 0°, 90°,
180° and 270°, 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.
