CommLink^TMDirect Digital Synthesizer

Features

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.

• 125MSPS Output Sample Rate with 5V Digital Supply

• 100MSPS Output Sample Rate with 3.3V Digital Supply

• 14-bit DAC with Internal Reference

• Parallel Control Interface for Fast Tuning (50MSPS Control

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.

• 48-bit Programmable Frequency Control

• Small 48-pin LQFP package

Applications

• Programmable Local Oscillator

• FSK Modulation

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.

• Direct Digital Synthesis

• Clock Generation
