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.
