Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
To achieve this RF performance, the tuner integrates a tracking filter and high-linearity front end.
Additionally, it reduces power consumption by eliminating the second frequency conversion used in many other silicon tuners.
Because it is a single-conversion tuner, the MAX3540 requires only a single SAW filter.
Incorporating both RF and IF AGC amplifiers, this device is ideal for televisions, set-top boxes and USB memory sticks.
The MAX3540 covers the full 54 to 860MHz frequency range, providing a standard 44MHz IF output that is compatible with almost all existing ATSC and NTSC demodulators.
This device operates from a single, 3.3V supply and is fully specified over the 0 to +85C temperature range.
The MAX3540 is available in a 7 x 7mm, 48-pin flip-chip package.
Prices start at US $5.90 (1000-up).
An evaluation kit is available to speed designs.
