Description

Leader in the low-cost FTA satellite market,

STMicroelectronics introduces its latest, low-cost

highly integrated solution for the retail market.

■ PAL/NTSC/SECAM encoder

– RGB, CVBS, Y/C and YUV outputs with

four 10-bit DAC outputs. RGB/CVBS or

YUV/CVBS or YC/CVBS

Offering

direct migration path from the

STx5118/STV0288 platform, The STx5188 uses

the same set of IPs, thereby facilitating the porting

from previous generations. It is based on the ST-

interconnect architecture and the popular ST20

CPU running at 200 MHz, and comes with a serial

and closed caption

■ Graphics/display

– Blitter-based display compositor

flash

interface.

The

embedded

QPSK

– 8 bpp CLUT graphics, 256 x 30-bit

(AYCbCr) CLUT entries or 16-bit true color

graphics, RGB565 and ARGB1555

formats. Link-list control

demodulator guarantees fast satellite scan times

thanks to the blind scan algorithm and a direct

connection to zero-IF tuners.

– 2-D paced blitter engine with fill function

– Multiple channel presentation
