The Intel CE 5038 DVB-S2 single-chip tuner is designed specifically for advanced modulation satellite set top boxes (STBs) meeting the DVB-S2 standard, which sets a performance benchmark for satellite set top boxes supporting high-data-rate HDTV and interactive services. The Intel CE 5038 DVB-S2 tuner delivers the high signal-to-noise and inter-modulation performance required to support 8-PSK and 16-QAM modulation schemes, allowing STB manufacturers to design DVB-S2 compliant products.
The Intel CE 5038 DVB-S2 tuner chip delivers excellent phase noise, integrated phase jitter, IQ imbalance and IP2 and IP3 immunity, which are key parameters to ensure that DVB-S2 signal-to-noise performance requirements are met. The Intel CE 5038 single-chip tuner provides manufacturers with a high-performance tuner solution that can be implemented simply and cost-effectively on the STB motherboard. In addition, the chip’s low-power modes help manufacturers design set top boxes that meet international energy-saving initiatives.
DVB-S2 Satellite Receiver Application
The Intel CE 5038 DVB-S2 tuner is an advanced modulation tuner device designed specifically for satellite set top boxes meeting the DVB-S2 standard. The higher data rates delivered by DVBS2 allow satellite service providers to roll out new applications, including HDTV services and satellite broadband access.
The Intel CE 5038 DVB-S2 tuner is a fully integrated single-chip wideband 8-PSK and 16-QAM compatible direct conversion tuner. As illustrated in the application diagram, the device integrates a LNA with a selectable RF loop-through for connecting to a second receiver module. It is a high-performance, alignment-free tuner solution, providing balanced I/Q signals to a DVB-S2 satellite demodulator.
The totally integrated phase-noise jitter performance of the on-chip local oscillator (LO) provides the carrier-to-noise margin required for difficult operating conditions. The Intel CE 5038 DVB-S2 tuner delivers a guaranteed maximum of 2 degrees of integrated phase jitter over the full operational temperature range.
The LO is designed to provide automatic and manual tuning modes to ensure optimum phase noise under all operating conditions. The automatic tuning mode is intended for 8-PSK modulation, while the manual tuning mode offers the flexibility required for 16-QAM modulation.
The Intel CE 5038 DVB-S2 tuner has excellent adjacent channel-interference protection, cable-slope handling and total composite power range, providing essential performance in today’s ever-changing broadcast environment. The device consumes less than 1.5 W, and is equipped with a hardware sleep pin and software programmable current reduction modes, enabling up to 60-percent reduction in power consumption. These power reduction features assist manufacturers in meeting Energy Star* requirements.

机顶盒采用软件技术实现数字电视即时CA解密（由于没有计算机的支持帮助）必须解决两个关键点：一是提高对信号处理的运算效率来达到和电视广播同步运行的匹配。其次为了保证CA不被破密的安全性，不能用降低CA抗破密的强度来凑合存储空间限制和运算效率，还不能提升机顶盒的成本(只能降低)。此外从长远发展来看，随着FTTH进一步的成熟普及和大容量存储器件的不断开发成功，它还可以起到家庭网关的作用（这方面的论述从略）。
一机顶盒从世界范围内广播电视发展方向看，模拟电视被数字电视取代是无庸置疑的，取代的时间和方法则随各国的国情而有所不同。但有一点可以肯定，无论经济实力有多雄厚，那国也不会于朝夕之间将所有模拟接收电视机都打入冷宫而以数字接收电视机来取代之，于是数/模转换机顶盒就应运而生。我国已经拥有三亿多台模拟接收电视机，当前我国有线电视由模拟向数字整体转换的关键条件
