The MAX2120 is ideal for DVB-S and free-to-air applications in which low cost and ease of use are key requirements
'Mobile TV is an exciting new market with potential applications in a variety of products from cellular phones to automobiles', explained Frank Prest, Business Manager for the company's TV and Radio Product line.
With a low 3.5dB noise figure that eliminates the need for an external LNA, the MAX2160 requires only capacitors, resistors and a crystal to complete the interface from a mobile UHF antenna to the digital baseband demodulator IC, forming a fully functional TV tuner.
Besides this impressive blend of simplicity and power, the MAX2160 achieves the other critical requirement for portable devices - long battery life - consuming less than 125W of continuous power.
The MAX2160 interfaces to a variety of baseband decoders.
The device uses a novel I/Q low-IF architecture allowing either one (I) or both (I and Q) outputs to be used.
This architecture achieves 55dB (typical) image rejection as well as +45dBc adjacent channel power handling.
Additionally, the low-IF architecture eliminates the need for a channel selecting SAW filter.
The SAW filter is replaced with on-chip bandpass filters.
The MAX2160ETL is specified for the extended industrial temperature range (-40 to +85C) and is offered in a 6 x 6mm, 40-pin thin QFN package.
Prices start at $4 in quantities of 100,000 and up.
'Initial customer reaction to our first true mobile TV tuner has been extremely positive', Prest added.
'We expect to build on our initial success with MAX2160 by introducing products for all worldwide mobile TV standards by the end of 2005'.
Samples are available for customer use now.
