Description

Leader in the low-cost FTA satellite market,

STMicroelectronics introduces its latest, low-cost

highly integrated solution for the retail market.

Offering

a

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

flash

interface.

The

embedded

QPSK

demodulator guarantees fast satellite scan times

thanks to the blind scan algorithm and a direct

connection to zero-IF tuners.
