STM5105

Low-cost interactive set-top box decoder

DATA BRIEF

DESCRIPTION

STMicroelectronics sets

STM5105 is supplied in either 24 mm x 24 mm

LQFP216 or 23 mm x 23 mm BGA package.

a new standard for

perfomance, price and integration in the single

chip MPEG-2 set-top box decoder market with the

introduction of the STM5105.

This highly integrated solution targets mass

market STBs, offers increased performance over

earlier devices, and includes many features to

further reduce costs, including a unified memory

architecture.

The STM5105 features the ST20 CPU that is

standard across the OMEGA range but boosts the

clock speed to 200 MHz which, when combined

with the 2D graphics engine, gives the new device

outstanding graphics performances.

Targeting low-cost, single tuner STB applications,

the STM5105’s DDR memory interface both

reduces system costs and minimises overall

system latency, ensuring the new device can

support the most demanding interactive TV

applications and middlewares.

xxxx

The integration of VCXO and audio DACs ensures

that manufacturers using the STM5105 cut their

bill of materials and significantly simplify board

design and assembly.
