| STM5105 Low-cost interactive set-top box decoder DATA BRIEF DESCRIPTION STMicroelectronics sets a new standard for perfomance, price and integration in the single chip MPEG-2 set-top box decoder market with the introduction of the STM5105. This highly integrated solution targets mass market STBs, offers increased performance over earlier devices, and includes many features to further reduce costs, including a unified memory architecture. The STM5105 features the ST20 CPU that is standard across the OMEGA range but boosts the clock speed to 200 MHz which, when combined with the 2D graphics engine, gives the new device outstanding graphics performances. Targeting low-cost, single tuner STB applications, the STM5105's DDR memory interface both reduces system costs and minimises overall system latency, ensuring the new device can support the most demanding interactive TV applications and middlewares. The integration of VCXO and audio DACs ensures that manufacturers using the STM5105 cut their bill of materials and significantly simplify board design and assembly. Figure 1. STM5105 low-cost interactive set-top box STM5105 is supplied in either 24 mm x 24 mm LQFP216 or 23 mm x 23 mm BGA package. xxxx stream in STV0299 and STB6000 STV0299 tuner and STB6000 tuner STV0297 QAM demodulator STV0297 + tuner QAM demodulator + tuner DRAM IR RX/TX Audio buffer OR STM5105 Video buffer STV0360 COFDM STV0360 + tuner COFDM + tuner Transport Smart card NOR Flash Rev. 1 March 2005 1/3 STM5105 FEATURES s Enhanced ST20 32-bit VL-RISC CPU - 200 MHz, single cycle cache, 4 Kbyte instruction cache, 4 Kbyte data cache, 2 Kbyte SRAM s s PAL/NTSC/SECAM encoder - RGB, CVBS, Y/C and YUV outputs with four 10-bit DAC outputs.
