11-bit 2.5-GSPS D/A converter increases number of QAM channels supported per D/A converter by up to 20 times.
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 speciality channels.
The AD9737A D/A converter features low noise and intermodulation distortion to enable high quality synthesis of wideband signals up to 1 GHz, reducing the number of transmit DACs required in the typical cable plant. The device operates from 1.8-V and 3.3-V supplies for a total power consumption of 1.1 W maximum.
The AD9737A benefits from a dual-port interface with double-data-rate LVDS data receivers that support the maximum conversion rate of 2.5 GSPS. A proprietary switching technique enhances dynamic performance. The devices output current is programmable from 8.7 mA to 31.7 mA adding flexibility in interface options.
Availability and Pricing
The AD9737A D/A converter packaged in a 160-ball CSBGA is available now and is in production. The device is priced at $37.14 each in 1000 quantities.
