GS12150
The GS12150 is a low-power, multi-rate reclocker that features both an integrated trace equalizer and trace driver, supporting rates up to 12G UHD-SDI, inclusive of 10GbE. It is designed to receive 100Ω differential input signals, automatically recover the embedded clock from the digital video signal and re-time the incoming data. Each of the 100Ω trace inputs supports up to 17dB of insertion loss.
The integrated eye monitor provides non-disruptive mission mode analysis of the post equalized input signal. The 256x128 resolution scan matrix allows accurate signal analysis to speed up prototyping and enable field analysis. Built in macros enable customizable cross section analysis and quick horizontal and vertical eye opening measurements.
With high phase consistency between scans and configurable space and time thresholds, algorithms can be deployed in the field to analyze long term signal quality variation (Bathtub Plot) to reduce costly system installation debug time for intermittent errors. The two independently controlled trace drivers have highly configurable pre-emphasis and swing controls to compensate for long trace and connector losses. The pre-emphasis pulse width and amplitude can be optimized to compensate for perturbations to frequency response of transmission lines due to vias, connectors and stubs.

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.
