Texas Instruments Introduces New High Performance, Lowest Power 12-Bit ADC for 3G Wireless Base Stations

6/27/2002 - Texas Instruments Incorporated (TI) (NYSE:TXN) introduced a new single-channel analog-to-digital data converter (ADC) that reduces typical power consumption by more than 50 percent. The new 12-bit 80 MSPS ADC consumes 360 milliWatts (mW) of power at full clock speed. The combination of best in class power savings and performance make this ADC ideal for micro and pico base stations as well as point-to-point microwave, portable instrumentation, medical imaging and digital cameras.

Performance Supports 2.5 and 3G Systems
TI´s new ADS5410 has spurious-free dynamic range of 75 decibels (dB) at 100 MHz and maintains input signal integrity beyond 200MHz IF. A signal-to-noise ratio of 60dB at 70 MHZ allows the ADS5410 to ensure signal accuracy. These low noise characteristics meet the specifications for base stations required by all of the world´s leading wireless standards, including W-CDMA, CDMA2000, IS-95, GSM, GPRS and EDGE.

“TI´s ADS5410 will help our customers minimize costs and power consumption in wireless micro and pico base stations," said Eduardo Bartolome, TI’s analog wireless infrastructure ADC systems engineering manager. "The performance of TI´s ADS5410 is exactly what is needed for GSM and WCDMA base stations."

Designed for flexibility
The ADS5410 offers features that make it flexible and easy to design with for wireless base stations and other new applications. A unique feature of the ADS5410 is the ability to handle adjustable 1.6V to 3.6V digital outputs, which allows the use of low-voltage logic. The ADC can be driven with a transformer, two single-ended OPA687 amplifiers or with TI´s latest high-speed differential amplifier, the THS4502. The differential and single-ended clock signaling allow for alternatives in clock supply. The output format of the ADS5410 is in 2s complement, providing the preferred output format to interface to with a digital signal processor (DSP) or application-specific integrated circuit (ASIC).

"The ADS5410 is the latest addition to a portfolio of products designed to enable system level solutions for wireless infrastructure applications,” Bartolome said.

These products include the industry´s highest performance DSPs, ASIC, power management products, digital upconverters and downconverters, data converters, high-speed amplifiers, interface solutions, and timing solutions. Among TI´s recent announcements are the DAC5675, a 14-bit, 400 MSPS multi-carrier digital-to-analog converter (DAC) and ADS5422, a 14-bit, 62 MSPS analog-to-digital converter.

The ADS5410 is TI´s latest addition to a large portfolio of products designed for use in wireless infrastructure, including the industry’s highest performance DSPs, ASIC, power management products, digital upconverters and downconverters, operational amplifiers and interface and timing solutions.

Availability, packaging, pricing
The new ADS5410 is now available in a 48-pin quad flatpack (PFB) from TI and TI authorized distributors. Suggested pricing is $23.00 in quantities of 1,000. An evaluation board is also available. See www.ti.com/sc/rd/ads5410pr for ordering information and to download a free datasheet today.
