GS3470
The GS3470 is a multi-rate SDI Receiver which includes complete SMPTE processing. The SMPTE processing features can be bypassed to support signals with other coding schemes. Multi-link UHD can be supported when multiple GS3470 devices are used.
The device features a dual input buffer with a 2x2 MUX. The 2x2 MUX can select between either input for de-serialization and can route either of the two inputs to the serial loopback independently (reclocked or non-reclocked). In addition, the integrated Re-timer with an internal VCO provides a wide Input Jitter Tolerance (IJT).
Configurable Power-down modes are available and allows for increased flexibility. Each Power-down mode enables power savings to a varying degree by selectively enabling or disabling key features. Some of the options available in Power-down mode are CSR access, PCLK, retimed SDO loop-through output, and non-retimed SDO loop-through output. Enabling or disabling each of these options will offer power consumption levels to suit the application's requirements.
The device has three other basic modes of operation which include:
- SMPTE mode
- DVB-ASI mode
- Data-Through mode
The GS3470 includes an audio de-embedder and audio clocks are internally generated. Up to eight channels (two audio groups) of serial digital audio may be extracted from the video data stream, in accordance with SMPTE ST 272-C and SMPTE ST 299.
New features and benefits vs. the existing solution:
- GS3470 has smaller package size, 9x9mm 100-ball BGA at 0.8mm ball pitch vs. GS2970A 11x11mm 100-ball BGA at 1mm ball pitch
- GS3470 has less power consumption, typical 220mW vs. GS2970A 350mW typical
- GS3470 fully supports 2K and multi-link UHD
- GS347x has two serial input ports and one internal 2x2 mux. The deserialized signal and the loop-through signal can be independently selected. GS2970A has only one serial input
- Eight configurable power-saving modes vs. GS2970A one standby mode

スタジアムの巨大スクリーンで野球の試合のアクションのリプレイを視聴する場合でも、大画面テレビで映画を視聴する場合でも、ノートパソコンでビデオをストリーミングする場合でも、高品質のオーディオビジュアル (AV) 体験が常に期待されています。デジタルAV伝送には、超高精細シリアルデジタルインターフェイス (UHD-SDI) と高解像度マルチメディアインターフェイス (HDMI) の2つの規格があります。UHD-SDIは、同軸または光ファイバーケーブルを介した非圧縮・非暗号化のデジタルAV信号の伝送を標準化します。HDMI は、HDMI準拠のソースからAVディスプレイに高解像度、高速デジタルマルチトラックオーディオおよび非圧縮ビデオ信号を送信するためのデジタルインターフェイスです。どちらも超高精細AV信号をソースからディスプレイに転送できますが、コンピューター、ゲーム機、Blu-ray/DVDプレーヤー、テレビ、プロジェクターなどの消費者向け機器の接続にはHDMIが好まれます。UHD-SDIは、ケーブル両端の物理的なロック機構で長距離伝送と堅牢な接続をサポートするため、プロの屋内/屋外ビデオ制作やテレビ放送などのハイエンドアプリケーションに適しています。UHD-SDI同軸ケーブルは最大300フィートの信号を転送できますが、HDMIケーブルは50フィート以内でも過度の信号劣化が問題となります。これら2つのインターフェイスは、HDMI-SDIまたはSDI-HDMIコンバーターを使って併用できます。例えば、図1のように、HDMIディスプレイはSDIストリームの信頼性監視に使用でき、この場合、特別に調整されたSDI固有のディスプレイを使用する必要がなくなります。

今すぐ読むI designed my first product using the Serial Digital Interface (SDI) back in 1996, and little did I know that this fledgling coax-based video interface standard would dominate my career for the next 20+ years. Back then, SDI was limited to carrying Standard Definition (SD) digital video at 270 Megabits per second (Mbps), but would evolve to higher and higher data rates to carry High Definition 720p, 1080i and 1080p, and most recently 4K Ultra High Definition (UHD) video, at cable lengths that were not thought possible. The convenience of a low cost single conductor coaxial copper cable, capable of carrying 4K video up to 100m has meant that SDI has become the de facto AV connectivity of choice in markets such as broadcast, Pro AV, medical and surveillance.
