PS8461V – DisplayPort Retimer with 2:1 Input Mux For Automotive Applications

PS8461V 是一款汽車級 DisplayPort 重定時器，具有整合的 2:1 輸入多工器。  它包括一個用於補償傳輸路徑損耗的輸入均衡器和一個重定時器電路，
用於消除訊號串擾和其他雜訊進入（包括 SoC DisplayPort 來源設備內耦合的雜訊）造成的隨機抖動。  穩定的內部時脈產生器用於重新產生無抖動的 DisplayPort 訊號。
支援高達 HBR3 (8.1Gbps) 的 DisplayPort 連結速率。 DisplayPort AUX 通道訊號監聽用於為下游 DisplayPort 接收器提供透明的鏈路訓練支持，
包括標準 DisplayPort 鏈路訓練協定和 LTTPR（鏈路訓練可調諧 PHY 中繼器）操作。
