GS12190
The GS12190 is a low-power, configurable multi-rate reclocking Cable Equalizer/Cable Driver supporting rates up to 12G UHD-SDI. It can be configured to equalize or drive signals over 75Ω coaxial cable. It includes DC restoration to compensate for the DC content of SMPTE pathological test patterns. Since the GS12190 is a reclocking device, extremely low output jitter is achievable even at extended cable/trace lengths. The device supports SMPTE ST 2082-1 (12G UHD-SDI), ST2081-1 (6G UHD-SDI), ST 424 (3G SDI), ST 292-1 (HD-SDI), and ST 259 (SD-SDI) signals and is optimized for performance at 11.88Gbps. In addition to standard SMPTE rates, the device also supports reclocking of DVB-ASI at 270Mbps, and MADI at 125Mbps. Each output has highly-configurable pre-emphasis and swing controls to compensate for long trace and connector losses. Additionally, automatic and user selectable output slew rate control is provided for the Cable Driver output.

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。

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.
