Elonics Introduces Low-Power DTV Tuner

Wednesday (Jan. 21) Elonics announced it has production released its E4000 tuner, which it claims is the “world's lowest power DVB-T/H terrestrial broadcast radio frequency tuner.”

It consumes 105 mW in continuous mode and 13 mW in the time sliced mode. Elonics said the E4000 “easily surpasses” the MBRAI 2.0 requirements for mobile devices and NorDig 2.0 for DTV applications.

The tuner has an impressive noise figure – 3.5 dB according to the E4000 CMOS Multi-Band RF Tuner product brief.

Elonics posted an interesting picture of the tuner low noise amplifier showing the inductor circuitry. This tuner represents the first use of Elonics proprietary “DigiTune” RF architecture allowing each stage of the RF signal processing to be adjusted under digital control. It is used to adjust the performance of the tuner for optimum linearity or noise figure according to signal conditions.

“The E4000 represents a very significant technological milestone in the industry by offering a substantial saving on power consumption versus competing solutions without sacrificing performance,” Elonics CEO David Srodzinski said. “This makes it ideal for the emerging worldwide digital TV market. The production launch of the E4000 also represents a very significant step forward for Elonics, marking the transition to a fully fledged product manufacturing operation allowing the company to rapidly increase its sales opportunity in the high volume consumer electronics business.”

The tuner is available now in production quantities.
