TUSB4020BI-Q1: The latency time between upstream and downstream

Part Number: TUSB4020BI-Q1

產品的應用是與Apple CarPlay相關,Apple CarPlay認證需要USB傳輸的Latency小於250ms.

所以想請教在TUSB4020BI-Q1在傳輸資料時的最大Latency Time是多少?

不管是Upstream to Downstream或是Downstream to Upstream的最大Latency(Delay) Time各是多少?

謝謝!

  • 您好 Nick,

    对于该类集线器产品,无法给出其Latency时间值,因为其延迟受到多种因素的影响,包括数据传输速率、总线带宽、集线器的性能以及设备的处理能力等。

    如果是USB控制器,一般会给出其Latency值。
