ISL5314
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.

NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-free
material sets, molding compounds/die attach materials, and 100% matte tin
plate plus anneal (e3 termination finish, which is RoHS compliant and
compatible with both SnPb and Pb-free soldering operations). Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.
