Description	STi5188

1 Description

Leader in the low-cost FTA satellite market, STMicroelectronics introduces its latest, lowcost highly integrated solution for the retail market.

Offering a direct migration path from the STi5118/STV0288 platform, The STi5188 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.

The STi5188 also includes audio DACs capable of direct connection to the TV input and the capability to operate from the same clock as the STV6110A. These cost reductions have been made without compromising ST quality standards and performance: 2-D graphics engine, faster CPU and built-in flexible DMA have been integrated.
