Demodulators support DVB-T, DVB-C and fixed DVB-H

Austin, Tex.—Silicon Laboratories Inc. has developed a pair of small, low-power digital video demodulators that supports DVB-T, DVB-C and fixed reception DVB-H in a single chip.

The Si2161 and Si2165 represent the first in a family of mixed-signal demodulators, tuners and receivers developed for digital and hybrid analog/digital fixed television equipment worldwide. The Si2161/2165 demodulators are suitable for equipment receiving digital terrestrial and/or cable services, including integrated digital televisions (iDTV), Free-to-Air (FtA) or pay-TV set-top box receivers, PC-TV add-on cards and DVD/HDD personal video recorders.

Both the Si2161 and Si2165 products operate natively in DVB-T mode, the most widely deployed terrestrial broadcast standard in the world, including Europe, Taiwan and Australia. The Si2165 adds the DVB-C demodulator mode used for unscrambled and pay-TV cable services.

Silicon Labs' Si2161 and Si2165 integrate 12-bit A/D converters that enable full flexibility in interfacing to any RF tuner whether standard IF, low IF or zero IF outputs. The Si2161/2165 also meet all of D-Book and NorDig 1.0.3 specifications.

The devices are packaged in a small, 5×6 mm, 36-pin QFN package. The Si2165 provides power dissipation of less than 130mW.

Pricing: In 10,000-unit quantities, the Si2161 starts at $2.90 and the Si2165, at $4.80.
Availability: Samples are available now.
