®

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.
