Overview
DESCRIPTION STMicroelectronics has developed two devices for low cost cable, satellite and terrestrial STBs.
The STi5516 and STi5517 integrate 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 STi5516 and STi5517 form a complete chipset for low-cost STBs across all application areas.
The STi5517 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 STi5517 has built-in D1 and PCM input interfaces to allow the IC to be used in applications requiring legacy analog support.
