Analog Devices’ D/A Converter Reduces Cable Head-End Signal Chain
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
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
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 GSPS.
- 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.
