Dual 16-bit DAC: JESD204B interface; up to 1.25 Gsps
Description
serial interface bus type
serial interface reset
coding of input word
IC power control
internal band gap power control
Description
NCO low power selection
modulation
NCO
inverse (sin x) / x function selection
4-wire SPI
3-wire SPI
no reset
performs a reset on all registers except address 00h
two’s complement coding
unsigned format
all circuits (digital and analog, except SPI) are in
power-down
all circuits (digital and analog, except SPI) are
switched on
band gap is power-down
internal band gap references are switched on
NCO disabled, the NCO phase is reset to 0
NCO enabled
low power NCO disabled
low power NCO enabled (frequency and phase
given by the five MSB of the registers 06h and 08h,
respectively)
disabled
enabled
dual DAC: no modulation
positive upper single sideband upconversion
positive lower single sideband upconversion
negative upper single sideband upconversion
negative lower single sideband upconversion
