RF DAC and Direct Digital Synthesizer
AD9164
When combined with a 100 MHz serial peripheral interface (SPI)
and fast hop modes, phase coherent fast frequency hopping (FFH)
is enabled, with several modes to support multiple applications.
In baseband mode, wide analog bandwidth capability combines
with high dynamic range to support DOCSIS 3.1 cable infrastruc-
ture compliance from the minimum of one carrier up to the full
maximum spectrum of 1.791 GHz of signal bandwidth. A 2×
interpolator filter (FIR85) enables the
AD9164
to be configured
for lower data rates and converter clocking to reduce the overall
system power and ease the filtering requirements. In Mix-Mode™
operation, the
AD9164
can reconstruct RF carriers in the second
and third Nyquist zones up to 7.5 GHz while still maintaining
exceptional dynamic range. The output current can be programmed
from 8 mA to 38.76 mA. The
AD9164
data interface consists of
up to eight JESD204B serializer/deserializer (SERDES) lanes
that are programmable in terms of lane speed and number of
lanes to enable application flexibility.
An SPI interface configures the
AD9164
and monitors the status of
all registers. The
AD9164
is offered in a 165-ball, 8 mm × 8 mm,
0.5 mm pitch CSP_BGA package, and a 169-ball, 11 mm × 11 mm,
0.8 mm pitch, CSP_BGA package, including a leaded ball option.
APPLICATIONS
Broadband communications systems
DOCSIS 3.1 CMTS/ video on demand (VOD)/edge
quadrature amplitude modulation (EQAM)
Wireless communications infrastructure
W-CDMA, LTE, LTE-A, point to point
GENERAL DESCRIPTION
The
AD9164
is a high performance, 16-bit digital-to-analog
converter (DAC) and direct digital synthesizer (DDS) that
supports update rates to 6 GSPS. The DAC core is based on a
quad-switch architecture coupled with a 2× interpolator filter
that enables an effective DAC update rate of up to 12 GSPS in
some modes. The high dynamic range and bandwidth makes
these DACs ideally suited for the most demanding high speed
radio frequency (RF) DAC applications.

For the lowest noise performance, use a separate power supply filter network for the VDD12_CLK and the VDD12A pins.

IOVDD can range from 1.8 V to 3.3 V, with ±5% tolerance.

The adjusted DAC update rate is calculated as f
DAC
divided by the minimum required interpolation factor. For the
AD9164,
the minimum interpolation factor is 1.
Therefore, with f
DAC
= 6 GSPS, f
DAC
adjusted = 6 GSPS. When FIR85 is enabled, which puts the device into 2× NRZ mode, f
DAC
= 2 × (DAC clock input frequency), and the
minimum interpolation increases to 2× (interpolation value). Thus, for the
AD9164,
with FIR85 enabled and DAC clock = 6 GSPS, f
DAC
= 12 GSPS, minimum interpolation = 2×, and
the adjusted DAC update rate = 6 GSPS.
