Product Summary
The STI5517PWA is a Low-cost set-top box decoder. It integrates more core STB functions into a single device than ever before, offering STB manufacturers the opportunity to build cost-effective solutions powered by devices from the leading supplier of MPEG-2 ICs. Used with ST’s established demodulator devices, the STI5517PWA form a complete chipset for low-cost STBs across all application areas. The STI5517PWA contains additional advanced features: it supports RGB16 graphics (with antiflicker filtering) as an alternative image format for the OSD plane. With an integrated highperformance DMA engine, it is ideal for applications requiring high-resolution graphics. The STI5517PWA has built-in D1 and PCM input interfaces to allow the IC to be used in applications requiring legacy analog support.
