Analog Devices’ D/A converter improves television viewing experience

July 11, 2016

Analog Devices Inc. (ADI) introduced a D/A converter that brings the future of television to today's home viewers, enabling them to enjoy ultra–high-definition (UHD) and 4K television across more channels at unprecedented streaming and download speeds. The new AD9162 D/A converter represents a breakthrough for the industry because it provides broadband and wireless service operators with the industry’s highest bandwidth and dynamic range to satisfy rising consumer demand for higher quality, always-on data and video streaming without requiring expensive, large-scale architecture or converter design changes. 

The 16-bit, 12-GSPS AD9162 converter’s best-in-class 2.5-GHz bandwidth exceeds the 1.794-GHz optional future requirement specified by the cable industry’s DOCSIS 3.1 standard by nearly 40 percent. The wider bandwidth affords cable operators the ability to plan next-generation network upgrades and capacity expansions without changing converter designs, which reduces product development time and engineering resources.

The AD9162 converter’s industry-best dynamic range (-82-dBc SFDR at -167-dBm/Hz NSD) allows designers to synthesize signals across a wide frequency spectrum from direct-to-RF up to 6 GHz. In wireless applications, this eliminates an IF-to-RF up-conversion stage and local oscillator generation, reducing base station component count, size and power consumption. The AD9162 supports all wireless communications infrastructure protocols (WCDMA, LTE, LTE-A, point-to-point), enabling advanced multiband and multi-standard radio designs.

Additional Features and Benefits

The AD9162 converter features a 2x interpolator (FIR85) that enables configurations for lower data rates and converter clocking to reduce overall system power and ease filtering requirements. In mix-mode operation, the RF D/A converters can be configured to reconstruct RF carriers in the 2nd and 3rd Nyquist zones up to 7.5 GHz while maintaining exceptional dynamic range.
