飞利浦半导体目前宣布推出业界首个可嵌入两个 DVB-S/DSS 信道解码器的集成电路。与传统的双信道接收器相比,这一款高度集成的 TDA10093HT 解决方案可大幅度降低卫星广播系统、机顶盒和电路的系统制造成本。TDA10093HT 芯片可广泛用于 DVB-S 和 DSS(数字卫星系统)接收器以及带接收器功能的时间转换盒和机顶盒。同时可实现画中画和个人视频录像机等功能。如果将TDA10093HT 芯片嵌在卫星机顶盒的硬盘中,那么观众即可在观看节目的同时录制节目。TDA10093HT 是基于 TDA10085HT 的新产品,采用小型 TOFP100封装,是卫星电视接收用的单芯片、双 QPSK(正交相移键控)信道接收器,它符合 DSS 和 DVB-S 标准。每个信道相互独立,并可通过 I~2C 总线编程。
Philips Semiconductors currently announces the industry’s first integrated circuit that can embed two DVB-S / DSS channel decoders. This highly integrated TDA10093HT solution significantly reduces system manufacturing costs for satellite radio systems, set-top boxes and circuits compared to traditional dual-channel receivers. The TDA10093HT chip is widely used in DVB-S and DSS (digital satellite system) receivers as well as time converter boxes and set-top boxes with receiver functions. At the same time can be achieved picture-in-picture and personal video recorders and other functions. If the TDA10093HT chip embedded in the satellite set-top box hard drive, then viewers can watch the program while recording the program. The TDA10093HT is a new product based on the TDA10085HT in a small TOFP100 package and is a single-chip, dual QPSK (Quadrature Phase Shift Keying) channel receiver for satellite television reception that conforms to the DSS and DVB-S standards. Each channel is independent of each other and can be programmed via the I ~ 2C bus.
