GENERAL DESCRIPTION
The AD9737A/AD9739A are 11-bit and 14-bit, 2.5 GSPS high
performance RF DACs that are capable of synthesizing wideband
and functionally compatible with the AD9739 with the
exception that the AD9737A/AD9739A do not support
synchronization or RZ mode, and are specified to operate
between 1.6 GSPS and 2.5 GSPS.
By elimination of the synchronization circuitry, some nonideal
artifacts such as images and discrete clock spurs remain stationary
allowing for possible system calibration. AC linearity and noise
performance remain the same between the AD9739 and the
The inclusion of on-chip controllers simplifies system integration.
A dual-port, source synchronous, LVDS interface simplifies the
digital interface with existing FGPA/ASIC technology. On-chip
controllers are used to manage external and internal clock domain
variations over temperature to ensure reliable data transfer from
the host to the DAC core. A serial peripheral interface (SPI) is
used for device configuration as well as readback of status
registers.
The AD9737A/AD9739A are manufactured on a 0.18 m
CMOS process and operate from 1.8 V and 3.3 V supplies.
They are supplied in a 160-ball chip scale ball grid array for
reduced package parasitics.
PRODUCT HIGHLIGHTS
1. Ability to synthesize high quality wideband signals with
bandwidths of up to 1.25 GHz in the first or second
Nyquist zone.
2. A proprietary quad-switch DAC architecture provides
exceptional ac linearity performance while enabling mix-
mode operation.
3. A dual-port, double data rate, LVDS interface supports the
maximum conversion rate of 2500 MSPS.
4. On-chip controllers manage external and internal clock
domain skews.
5. Programmable differential current output with an 8.66 mA
to 31.66 mA range.
