High Speed Digital to Analog Converters

The Pico E-15 features 2 high speed analog to digital converters. The converters are optimized for high-frequency, high-performance, low-power, low-noise operation. The converters have integrated DC blocking capacitors, and can not be used on low frequency signals. The DAC should be terminated into a 50 ohm load.

To ensure accuracy at high speeds, the low-jitter 125 MHz reference clock must be used. The DAC supports a clock frequency of up to 210 MHz.
