SLLSF36A August 2017 – September 2017 TUSB214-Q1
The USB signal trace must not be broken when placing TUSB214-Q1. Thus, even with the TUSB214-Q1 powered down, or not populated, the USB link is still fully operational. To avoid the need for signal vias, it is highly recommend to route the High Speed traces directly underneath the TUSB214-Q1 package, as illustrated in the PCB land pattern shown in Figure 22.
Although the land pattern shown below has matched trace width to pad width, optimal impedance control is based on the user's own PCB stack-up. It is recommended to maintain 90 Ω differential routing underneath the device.
All dimensions are in millimetres (mm).
