Analog Devices’ D/A Converter Reduces Cable Head-End Signal Chain Footprint
January 13, 2012 Press Release-- 11-bit AD9737A 2.5-GSPS D/A converter
increases number of QAM channels supported per D/A converter
by up to 20 times.
January 13, 2012
NORWOOD, Mass.--(BUSINESS WIRE)-- Analog Devices, Inc. (ADI),
the data converter market share leader, today introduced an 11-bit D/A converter that enables cable television and
broadband operators to synthesize the entire cable spectrum up to 1 GHz into a single RF port, while consuming a
maximum of 1.1 W of power. The
AD9737A 2.5-GSPS D/A converter’s wide bandwidth and
dynamic range enable cable infrastructure designers to increase QAM (quadrature amplitude modulation) channel
density by 20 times over present cable modem implementations, enabling improved next-generation services such as
interactive television, high-definition broadcasts and new specialty channels.

AD9737A D/A Converter Features and Benefits:
Pricing, Availability and Complementary Products
- Low noise and intermodulation
distortion enable high quality synthesis of wideband signals up to 1 GHz, reducing the number of transmit DACs
required in the typical cable plant.
- Operates from 1.8-V and 3.3-V supplies for a total power consumption of 1.1 W maximum.
- Dual-port interface with double-data-rate LVDS data receivers supports the maximum conversion rate of 2.5
- Proprietary switching technique enhances dynamic performance.
- Output current is programmable from 8.7 mA to 31.7 mA adding flexibility in interface options.
- Not subject to US data converter export restrictions.
Complementary components include ADI’s ADCLK914
clock/data buffer that drives the clock input of the AD9737A D/A converter with a 2 V differential swing that
achieves jitter performance of 110 fs.
Data Converters: Bridging the Analog and Digital Worlds More
designers turn to Analog Devices than any other supplier for the high-performance conversion technology required
to bridge the analog and digital worlds in today’s myriad electronic systems. With the industry’s leading
A/D Converters (analog-to-digital converters) and
D/A Converters (digital-to-analog converters),
Analog Devices’ converter products feature the right combination of sampling rates, accuracy, and reduced noise,
power, price, and package size required in industrial and instrumentation, medical equipment, automotive systems,
communications infrastructure, and consumer electronics.
