STMicroelectronics today unveiled two new System-on-Chip ICs that allow standard-definition (SD) or high-definition (HD) equipment to share the same printed-circuit-board (PCB) design and leverage software developed for earlier product generations. The STi7162 for HD STBs and STi5262 for SD products are based on the widely used STi7167 and STi5267, respectively. Targeting free-to-air, cable and terrestrial STBs, as well as hybrid products with added support for IPTV, each device combines the STB decoder with DVB-C cable and DVB-T terrestrial demodulators, plus optional Ethernet support. Each device supports targeted functions for cost-optimized STBs with built-in security features.
The STi7162 and STi5262 have identical pin assignments, allowing manufacturers to save the costs of developing a separate PCB for SD and HD products. Each chip also simplifies PCB design and reduces build costs.
