AD9958BCPZ-REEL7

AD9958 2-channel, 500MSPS DDS with 10bit DAC. It consists of two 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 analogue processing, such as filtering, amplification or PCB layout related mismatches. Because both channels share a common system clock, they are inherently synchronized. Synchronization of multiple devices is supported. Typical applications include Agile local oscillators, phased array radars/sonars, instrumentation, synchronized clocking, RF source for AOTF, single-side band suppressed carriers and quadrature communications.

• 2 synchronized DDS channels at 500MSPS
• Independent frequency/phase/amplitude control between channels
• Matched latencies for frequency/phase/amplitude changes
• Excellent channel-to-channel isolation (<gt/>72 dB)
• Linear frequency/phase/amplitude sweeping capability
• Up to 16 levels of frequency/phase/amplitude modulation (pin-selectable)
• Individually programmable DAC full-scale currents
• 0.12Hz or better frequency tuning resolution, 14/10bit phase offset/amplitude scaling resolutions
• 56 lead LFCSP_VQ package
• Operating temperature range from -40°C to 85°C
