Called EV12DS460, conversion is 12bit at at 6Gsample/s guaranteed, with operation possible up to 7Gsample/s.
“Removing up-conversion stages in our customers’ systems operating up to K-band will help them simplify system design,” said company v-p semiconductors Laurent Monge.
7.5 GHz of analogue output bandwidth is available to -3dB, with 30ps rise and fall times.
RF signal synthesis up to 12GHz (X‐band) is supported, as is synthesis up to 24GHz with reduced output power.
“EV12DS460 contains the largest choice of DAC settings to optimise performance up to 26.5GHz,” said the firm. “It is also equipped with four different output modes [NRZ, RTZ, NRTZ and RF] allowing performance optimisations depending on the Nyquist zone of interest, and includes an option for program pulse shaping, making it proficient at handling the most specific of RF applications.”
Three rails are needed: 3.3V for logic, and 3.3V as well as 5V for analogue. Power dissipation is under 3W.
