STi5100
®
Low-cost interactive set-top box decoder
DATA BRIEF
Description
.
The STi5100 provides the power and features
required to meet the specifications of the most
demanding broadcasters and can be used in
satellite, terrestrial, cable or IP set-top boxes. The
STi5100 also provides a USB2.0 host interface
which allows consumers to connect a wide range of
peripherals to their STB such as digital cameras,
memory sticks, printers and hard disk drives for DVR
applications
The STi5100 features the ST20 CPU that is
standard across the OMEGA range but boosts the
clock speed to 243MHz which, when combined with
the DDR memory interface, gives the new device
exceptional levels of performance. The new chip
also includes a unified DDR memory interface and a
modem interface compatible with Silicon
Laboratories’ silicon DAA.
