TV Tuner Solutions

The RadiX tuner is the industry’s lowest power and most highly integrated CMOS based multi-standard silicon TV tuner enabling the lowest bill of materials. With built-in SAW filters, the RadiX supports digital TV standards such as ATSC (8-VSB), DVB-T and DVB-C, analog TV standards such as NTSC, PAL and SECAM, as well as FM radio formats.

The RadiX TV Tuner is based on the ESS patented Direct Sampling Mixer (DSM) plus 18 more patent-pending circuits including: Channel Selection Filter, Virtual Weaver architecture, and Advanced High Resolution Synthesizer. It uses a fast systolic analog array integrated in a discrete signal processing engine and a digital signal processing unit to tune the channels. The result is a high performance, low-power tuner with an extremely fast channel locking time. The discrete signal processor replaces several power hungry blocks found in traditional tuner. This technology dramatically reduces the power consumption of the tuner to less than 400 mW. A sleep mode can be enabled for a minimal 1.2 mW power consumption.
