Giga Sample (GSPS) Analog-to-Digital Converters (ADCs)

Industry's Fastest 12-bit ADC Family Enables a New Generation of SDR Architectures

Texas Instruments enables a new generation of high dynamic range, wide bandwidth software-defined radio (SDR) architectures and applications.

With the industry's fastest 12-bit ADC family, ADC12D1800/1600/1000, TI continues to expand its portfolio of GSPS ADCs which pair with TI's wideband amplifiers and low-noise clock & timing solutions to meet SDR's need for superior analog performance to recover data with very high sensitivity from multiple channel and RF applications requiring:

• Wide input bandwidth
• Frequency flexibility
• Multiple mixing stages
• Simultaneous reception of multiple channels or band-limited signals
• Any combination of the above

Key Applications

• Wideband communications
• Multi-standard/multi-carrier base stations
• Military communications/signal intelligence
• Data acquisition
• RADAR/LIDAR
• Optical networks
• Microwave backhaul
• Multi-tuner set-top boxes

Software-Defined Radio vs Traditional Hardware-Defined Radio

In multi-channel and RF systems, hardware defined radio (HDR) implementations require a significant amount of analog signal processing for every channel, leading to larger board size, increased analog design complexity, limited flexibility, and RF interference susceptibility.

With the SDR approach, signal processing is moved to the digital domain—providing various benefits:

• Low analog complexity
• Less susceptibility for RF interference
• Unlimited flexibility
• Analog power does not increase with increased Rx channels

• High analog complexity
• RF interference susceptibility
• Limited flexibility
• Redesign required for any additional features
• Analog power, area and weight scales with channels

• Low analog complexity
• Less susceptibility to RF interference
• Unlimited flexibility
• Analog power does not increase with increased Rx channels
• Low power, small size, and lighter weight
