EV12DS400A

EV12DS400AVZPY12-bit DAC provides high levels of spectral purity from 0 to 7GHz

This ground breaking DAC provides an analog bandwidth extending beyond 7GHz facilitating multi-band, direct digital synthesis in the L, C and S-bands. Furthermore 30ps rise/fall times also makes this part ideal in time domain applications. A flexible 4:1 or 2:1 input multiplexer enables sampling rates up to 4.5 GSPS.

Four output coding modes (NRZ, RTZ, NRTZ and RF) offer design flexibility and helps simplify frequency planning. This unique part can deliver spectral power up to and beyond the fourth Nyquist zone (see charts below). The DAC achieves > 50dB NPR and high spectral purity with an SFDR of 65dBc@2240MHz.

The EV12DS400 offers features to simplify design-in for many sophisticated RF systems.

Nyquist zone Output mode NPR ENOB
NZ1 NRTZ 47.5 dB 9.4 bit
NZ2 NRTZ 42 dB 8.5 bit
NZ3 RF 39 dB 8 bit
