TI Introduces Two New High Performance 11-Bit, 125- and 200-MSPS ADCs for the China Market

ADCs Complete Wireless Infrastructure Signal Chain for China TDS-CDMA Applications

DALLAS, Dec. 17 /Xinhua-PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced two new high-performance 11-bit analog-to-digital converters (ADC) for the China market. The two-channel, 125-mega samples per second (MSPS) ADS62C15 and single-channel, 200-MSPS ADS5517 are designed to provide the highest combination of resolution and sample rate available in China for wireless infrastructure equipment, low-power automated test equipment, and general-purpose data acquisition equipment. The latest ADC offering from TI advances the signal chain for TDS-CDMA applications in the China marketplace. (For more information, see http://www.ti.com/ads62c15-pr ).

ADCs Increase Bandwidth for TDS-CDMA Market

The ADS62C15 offering from TI delivers on the need for increased bandwidth in the cellular infrastructure market by increasing performance as much as 7 dB over previous 11-bit converters. The ADS62C15 features TI's SNRBoost technology, providing a lower noise floor and higher receiver sensitivity for applications that require up to 20 MHz of signal bandwidth. This technology provides signal-to-noise ratio (SNR) characteristics similar to a 14-bit converter in limited bandwidth applications, but with only an 11-bit output. For instance, in an applications requiring 10 MHz bandwidth, such as diversity receivers, the ADS62C15 achieves 75 dBFS SNR in default mode and can reach 82 dBFS SNR with SNRBoost.

The ADS5517 is the first 11-bit ADC available in a space-saving 7-mm x 7-mm package that is able to operate at 200 MSPS. The ADS5517 provides the bandwidth necessary for linearizing the performance of transmit power amplifiers in digital pre-distortion (DPD) solutions, enabling OEMs to produce more efficient transmit solutions.

TI Advances Signal Chain Solution for Wireless Infrastructure

The ADS62C15 and ADS5517, coupled with other critical components of the transceiver chain including the DAC5687, TRF3710, TRF3703, GC5016 and THS45xx family of amplifiers, provides a complete solution for DPD transmit and multi-carrier receive signal chains. The solution also works with TI's family of single- and multi-core wireless infrastructure-optimized digital signal processors. TI is the industry leader in both 2G and 3G markets, with eight out of the top eight base station OEMs deploying TI technology.

Evaluation Tool Reduces Time to Market

To further simplify design and speed development time, TI offers the TSW1100 digital data capture evaluation tool. Designed to work directly with the evaluation modules (EVMs) of TI's single- and dual-channel ADCs, the TSW1100 comes with software that allows the user to quickly evaluate ADCs without the need for expensive logic analyzers and complex analysis routines. For more information, see http://www.tsw1100digitalcapture .

In addition to the TSW1100, TI offers analog engineers a wide-ranging support infrastructure. For more information on TI's complete analog design support, and to download the latest Amplifier and Data Converter Selection Guide, visit http://www.ti.com/analogelab .

Pricing and Availability

The ADS5517 is available now in a 7-mm x 7-mm quad flat no-lead (QFN) package and the ADS62C15 will be available in 1Q2008 in a 9-mm x 9-mm QFN package. Suggested retail pricing is $41.15 for the ADS5517 and $51.55 for the ADS62C15 in 100-unit quantities. Samples and EVMs are available.
