The recommended power-up sequence is to apply the analog supply voltage (AVCC) first, followed by the digital supply voltage (DVCC), and then the clock signal. This ensures proper initialization of the device.
To ensure accurate voltage output, it is essential to use a low-noise, low-impedance voltage reference, and to decouple the analog supply voltage (AVCC) with a 10uF capacitor. Additionally, the output voltage should be filtered with a low-pass filter to reduce noise and ripple.
The DAC5652AIPFB can handle clock frequencies up to 100 MHz. However, it is recommended to use a clock frequency of 50 MHz or less to ensure optimal performance and to minimize jitter and noise.
To synchronize multiple DAC5652AIPFB devices, connect the SYNC pin of each device to a common clock signal. This ensures that all devices are clocked simultaneously, and their outputs are synchronized.
The SYNC pin is used to synchronize the DAC's output with an external clock signal. When the SYNC pin is high, the DAC's output is updated on the rising edge of the clock signal. This allows multiple DACs to be synchronized and ensures that their outputs are updated simultaneously.
