Speedy ADC claims top dynamic
performance
A new 14bit, 170Msample/s analogue-to-digital convertor claims unmatched dynamic performance.
Extending its family of leading-edge high-speed data convertors, Texas Instruments has released a 14bit, 170Msample/s analogue-to-digital convertor (ADC) claiming unmatched dynamic performance The ADS5545 offers 72dB full-scale signal-to-noise ratio (SNR) and 84dBc spurious-free dynamic range (SFDR) at the maximum sample rate of 170Msample/s and an input frequency of 150MHz, providing increased system capabilities in advanced communications, instrumentation, test and measurement, medical, video and imaging applications

Texas Instruments has introduced the industry's first 0- to 4-Gbps data buffer/signal conditioner with a dual multiplexer.
Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
"The ADS5545 builds on the leadership performance of the ADS5500 14bit, 125Msample/s ADC by offering best-in-class performance in a 7 x 7mm QFN package with only 1W core power dissipation", said Roberto Sadkowski, Business Unit Manager for TI's high-speed ADCs.
"This new device enables a wide range of benefits such as improved receiver capabilities in wireless communications, higher quality imaging in video systems and extended signal analysis for test equipment".
The device includes an internal sample and hold, low-jitter clock buffer, internal reference, and options for parallel CMOS or LVDS outputs.
It operates from a single 3.3V supply and is specified over the industrial temperature range of -40 to +85C.
TI provides customers a state-of-the-art signal chain for wideband applications with high-speed amplifiers (THS4509, OPA847), high-speed digital-to-analogue convertors (DAC5687), digital up/down convertors (GC5016), crest factor reduction processors (GC1115) and quadrature modulators (TRF3701, TRF3702).
The ADS5545 is also optimised to work with TI's high-performance TMS320C6x DSP platform.
The ADS5545 is sampling now, with volume production scheduled for Q2 2006.
The device comes in a 48-pin QFN package (7 x 7mm) and is priced at $62.50 in 1000 piece quantities (suggested resale pricing).
