Direct Digital Synthesizer  
Features  
The 14-bit ISL5314 provides a  
complete Direct Digital Synthesizer  
(DDS) system in a single 48-pin  
• 125MSPS output sample rate with 5V digital supply  
• 100MSPS output sample rate with 3.3V digital supply  
• 14-bit digital-to-analog (DAC) with internal reference  
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.  
• Parallel control interface for fast tuning (50MSPS control  
register write rate) and serial control interface  
• 48-bit programmable frequency control  
• Offset frequency register and enable pin for fast FSK  
• Small 48-pin LQFP packaging  
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 degrees, while the ENOFR pin enables or  
zeros the offset frequency word to the phase accumulator.  
Applications  
• Programmable local oscillator  
• FSK, PSK modulation  
• Direct digital synthesis  
• Clock generation  
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.
