Product Summary
The AD9958BCPZ is a 2-Channel 500 MSPS DDS with 10-Bit DACs. The AD9958BCPZ 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 analog processing such as filtering, amplification, or PCB layout related mismatches. Since both channels share a common system clock, they are inherently synchronized. Synchronization of multiple devices is supported.
