AD9959BCPZ-REEL7

AD9959 consists of four direct digital synthesizer (DDS) cores that provide independent frequency, phase, and amplitude control on each channel. This flexibility can be used to correct imbalances between signals due to analog processing, such as filtering, amplification, or PCB layout-related mismatches. The AD9959 can perform up to a 16-level modulation of frequency, phase, or amplitude (FSK, PSK, ASK). Modulation is performed by applying data to the profile pins. Typical applications include agile local oscillators, phased array radars/sonars, instrumentation, synchronized clocking and RF source for AOTF.

• Dual supply operation (1.8 V DDS core/3.3 V serial I/O)
• Independent frequency/phase/amplitude control between channels
• Matched latencies for frequency/phase/amplitude changes
• Excellent ch-to-ch isolation (<gt/>65dB) and linear frequency/phase/amplitude sweeping capability
• Up to 16 levels of frequency/phase/amplitude modulation
• 4 integrated 10-bit DAC and individually programmable DAC full-scale currents
• 0.12Hz or better frequency tuning resolution, 14bit phase offset resolution
• 10bit output amplitude scaling resolution and Multiple device synchronization
• Software-/hardware-controlled power-down, Selectable REFCLK crystal oscillator
• 56 lead LFCSP_VQ package, operating temperature range from -40°C to 85°C
