ISL5314
Direct Digital Synthesizer
The 14-bit ISL5314 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. 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.
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.
