Digital to analog converter
e2v has introduced the next generation 10-bit GSPS DAC EV10DS130A, (GSPS-giga-sample per second) designed for demanding Software Defined Microwave systems and arbitrary waveform generation with very sharp rise and fall times.
The EV10DS130A operates with a sampling speed of 3 GSPS and generates signals at microwave frequencies up to C-band. Applications operating in the first Nyquist zone will benefit from a very flat frequency response, while time-domain applications will benefit from a sub-50ps full-scale-rise/fall-time. Even with its microwave capabilities, power consumption is low at 1.3 W.
For performance optimization from dc up to 7 GHz, this digital to analog converter (DAC) has four selectable modes, against the chosen Nyquist zone of operation: Return-to-zero, non-return-to-zero, narrow-return-to-zero and RF mode.
EV10DS130A is an all-European export licence free device. Its IP content is from e2v’s Grenoble, France facility and the silicon foundry technology employed is the B7HF200 process from Infineon in Regensburg, Germany.
The EV10DS130A is offered in a small footprint FpBGA 196 package (15 x 15 mm) with the choice of commercial temperature grade (0 C to +90 C) and industrial temperature grade (-40 C to +110 C).
