GENERAL DESCRIPTION
The AD9119/AD9129 are high performance, 11-/14-bit RF digital-
to-analog converters (DACs) supporting data rates up to 2.8 GSPS.
The DAC core is based on a quad-switch architecture that enables
dual-edge clocking operation, effectively increasing the DAC
update rate to 5.6 GSPS when configured for Mix-Mode™ or 2×
interpolation. The high dynamic range and bandwidth enable
multicarrier generation up to 4.2 GHz.
In baseband mode, wide bandwidth capability combines with high
dynamic range to support from 1 to 158 contiguous carriers for
CATV infrastructure applications. A choice of two optional 2×
interpolation filters is available to simplify the postreconstruction
filter by effectively increasing the DAC update rate by a factor of 2.
In Mix-Mode operation, the AD9119/AD9129 can reconstruct
RF carriers in the second and third Nyquist zone while still
maintaining exceptional dynamic range up to 4.2 GHz. The
high performance NMOS DAC core features a quad-switch
architecture that enables industry-leading direct RF synthesis
performance with minimal loss in output power. The output
current can be programmed over a range of 9.5 mA to 34.4 mA.

The AD9119/AD9129 include several features that may further
simplify system integration. A dual-port, source synchronous
LVDS interface simplifies the data interface to a host FPGA/ASIC.
A differential frame/parity bit is also included to monitor the
integrity of the interface. On-chip delay locked loops (DLLs)
are used to optimize timing between different clock domains.
A serial peripheral interface (SPI) is used to configure the
AD9119/AD9129 and monitor the status of readback registers.
The AD9119/AD9129 is manufactured on a 0.18 µm CMOS
process and operates from +1.8 V and −1.5 V supplies. It is
supplied in a 160-ball chip scale package ball grid array.
PRODUCT HIGHLIGHTS
1. High dynamic range and signal reconstruction bandwidth
support RF signal synthesis of up to 4.2 GHz.
2. Dual-port interface with double data rate (DDR) LVDS
data receivers supports 2800 MSPS maximum conversion rate.
3. Manufactured on a CMOS process; a proprietary switching
technique enhances dynamic performance.
