FEATURES AND BENEFITS

? Quad channel 16-bit resolution

? 2 GSps maximum output update rate

? JEDEC JESD204B device subclass I compatible:

SYSREF based deterministic and repeatable interface

latency

? Multiple device synchronization enables multiple DAC

channels to be sample synchronous and phase coherent

to within one DAC clock period

? Up to 8 configurable JESD204B serial input lanes

running up to 10 Gbps with embedded termination and

programmable equalization gain (CTLE)

? SPI interface (3-wire or 4-wire mode) for control setting

and status monitoring

? Flexible SPI power supply (1.8 V or 1.2 V) ensuring

compatibility with on-board SPI bus

? Differential scalable output current from 10 mA to 30 mA

? Two embedded NCO with 40-bit programmable

frequency and 16-bit phase adjustment

? Embedded complex (IQ) digital modulator

? Very low noise bypass-able integrated Phase-Locked

Loop (PLL); no external capacitors

? 1.2 V and 3.3 V power supplies (for DAC1653Q series,

the 3.3V supply voltage can be lowered to 2.8V for lower

power consumption)

? Flexible differential SYNC signals power supply (1.8 V or

1.2 V) ensuring compatibility with on-board devices

? Embedded Temperature Sensor

? Configurable IOs pins for monitoring, interrupt
