4-Channel, 500 MSPS DDS

with 10-Bit DACs

AD9959

Software-/hardware-controlled power-down

Dual supply operation (1.8 V DDS core/3.3 V serial I/O)

Multiple device synchronization

Selectable 4× to 20× REFCLK multiplier (PLL)

Selectable REFCLK crystal oscillator

56-lead LFCSP package

FEATURES

4 synchronized DDS channels @ 500 MSPS

Independent frequency/phase/amplitude control between

channels

Matched latencies for frequency/phase/amplitude changes

Excellent channel-to-channel isolation (>65 dB)

Linear frequency/phase/amplitude sweeping capability

Up to 16 levels of frequency/phase/amplitude modulation

(pin-selectable)

4 integrated 10-bit digital-to-analog converters (DACs)

Individually programmable DAC full-scale currents

0.12 Hz or better frequency tuning resolution

14-bit phase offset resolution

APPLICATIONS

Agile local oscillators

Phased array radars/sonars

Instrumentation

Synchronized clocking

RF source for AOTF

10-bit output amplitude scaling resolution

Serial I/O port interface (SPI) with enhanced data throughput
