Elonics Releases E4001 Dual Band Digital Terrestrial TV Tuner

Very Low Power/Cost Solution For STB and TV Modules

Elonics, the RF semiconductor company, has production released the E4001, a highly integrated dual-band RF tuner IC implemented in CMOS, ideal for digital TV and radio broadcast receiver solutions. Taking features from Elonics highly respected E4000 device which was launched last year, the E4001 has been specifically developed for STB and TV modules.

The digitally programmable tuner architecture covers the complete spectrum from VHF to UHF (64MHz to 858MHz). This flexibility allows the user to re-configure the RF front end for different broadcast standards.

At the heart of the E4001 is Elonics innovative DigitalTune™ architecture, which allows the designer to adjust the performance of the tuner for optimum linearity or noise figure according to the signal conditions. It enables manufacturers to significantly improve reception quality whilst supporting multiple broadcast standards including DVB-T, ISDB-T, D-TMB, and CMMB.

The E4001 tuner uses a zero IF architecture, which dramatically reduces the number of external components and allows power consumption to be minimised to as low as 100mW. It makes the E4001 a cost effective and very low power solution for the digital TV market.

“Elonics E4001 continues the development of the E4000 family using our DigitalTune™ technology to further tailor our offerings to resolve specific issues for tomorrow’s applications. The E4001 presents a compelling solution for TV applications as consumer hunger for the new digital TV services continues to develop at a rapid pace,”
said David Srodzinski, CEO Elonics.
