SoC ICs for cable and terrestrial set-top boxes
ST Microelectronics
STi7162 and STi5262, two System-on-Chip ICs
STMicroelectronics has unveied the STi7162 and STi5262, two System-on-Chip ICs allowing standard-definition (SD) or high-definition (HD) equipment to share the same printed-circuit-board (PCB) design.
The STi7162 for HD set-top boxes (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, in addition to optional Ethernet support.
Each device supports targeted functions for cost-optimised 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.
In addition, each chip simplifies PCB design and reduces build costs, as the pin assignments allow a straightforward two-layer board instead of a complex and expensive multi-layer board.
Software compatibility between the latest devices and the STi7105 and STi7167 enables project teams to reuse existing software and thereby focus development resources on creating innovative, value-added features.
