SI21682-D60集成电路（IC）的视频处理规格书PDF中文资料

SI21682-D60属于集成电路（IC）的视频处理。由美国思佳讯公司制造生产的SI21682-D60视频处理一种集成电路 (IC) 半导体器件，设计用于在放大、增强、编码器和解码器（编解码器）、缓冲、校准、处理、信号调节、调制与解调、转换、传输、伽玛校正、切换、OSD、数字化和多路复用等应用中处理音频和/或视频信号。

描述 Description

The Si21682D integrates two separate high-performance digital

demodulators for the DVB-T2/T and DVB-C standards into a single

compact package. Leveraging Skyworks' proven digital

demodulation architecture, the Si21682D achieves excellent

reception performance for each media while significantly

minimizing front-end design complexity, cost, and power

dissipation. Connecting the Si21682D to a dual terrestrial/cable TV

tuner results in a high-performance and cost optimized TV frontend

solution.

Skyworks’ internally-developed DVB-T2 (including T2-Lite)

demodulators support all modes specified by the DVB-T2 standard

V1.4.1). Main features of the DVB-T2 mode are, SISO and MISO

support, FEF management, fully autonomous signal acquisition

including automatic L1 signaling parsing support for all pilot

patterns, and DVB-T2/T auto-detection.

The DVB-T and DVB-C, including ITU-T J.83 annex B,

demodulators are enhanced versions of proven and broadly used

Si2164/67/68/69 Skyworks devices.

The Si21682D offers an on-chip blind scanning algorithm for the

DVB-C standard, as well as blind lock function. The Si21682D

embeds two independent programmable transport stream

interfaces which provide a flexible range of output modes,

including a cross-bar functionality, and are fully compatible with all

MPEG decoders or conditional access modules to support any

customer application.
