Elonics has introduced the E4001, an integrated dual-band RF tuner IC implemented in CMOS.

Taking features from Elonics’ 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 (64 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’ 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 improve reception quality while 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 low-power solution for the digital-TV market.
