ADC claims best-in-class dynamic
performance
A new 14bit 190Msample/s analogue-to-digital convertor boasts outstanding dynamic performance and low total power dissipation.
Using its high-performance analogue design expertise, Texas Instruments has released a 14bit, 190Msample/s analogue-to-digital convertor (ADC) with outstanding dynamic performance and low total power dissipation The ADS5546 offers 73.2dB FS signal-to-noise ratio (SNR) and 84dBc spurious-free dynamic range (SFDR) at the maximum sample rate of 190Msample/s with an input frequency of 70MHz, making it ideal for wireless communications, video and imaging, test and measurement, and instrumentation applications

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 ADS5546 features best-in-class dynamic performance, only 1.1W total power dissipation and small 7 x 7mm QFN packaging, which allows our customers to deliver new capabilities and features in their advanced applications", said Kent Novak, General Manager for TI's high-speed products.
The ADS5546 complements TI's family of high-performance ADCs to provide designers with a range of resolutions, speed and performance options tailored to their application requirements.
Each device offers superior dynamic performance and high IF capability.
The ADS5546 offers unprecedented interface flexibility with user-selectable CMOS or DDR LVDS outputs.
The device includes an internal sample and hold, low-jitter clock buffer and internal or external reference capability.
The device provides a unique set of value added features, such as programmable power scaling and user-selectable output timing and level controls.
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), quadrature modulators (TRF3701, TRF3702) and PLLs (TRF3750, TRF3761).
The ADS5546 is also optimised to work with TI's high-performance DSP platforms.
The ADS5546 is sampling now, with volume production scheduled for 2Q 2006.
The device comes in a 48-pin QFN package (7 x 7mm) and is priced at $72.50 in 1000-piece quantities (suggested resale pricing).
Evaluation modules (EVMs) are also available.
