Other Parts Discussed in Thread: TUSB211, TPS2546
Hi,
When use TUSB211-Q1,we met the failure in Eye Diagram test. Schematic/PCB and measured Eye Diagram as attachment. There seems to be uncommonly attenuation, and I am doubtful if it cause by Common COMMON MODE ESD FILTER. Can you give some advice please? and how can i improve it? Thanks!
Remark:
1/ The TUSB211 following with TPS2546, and output to USB socket;
2/ It is TEF1210A2X500MT for COMMON MODE ESD FILTER;
3/ The white line in PCB is USB route.
