For best performance, it is recommended that the trace impedance for differential signals as in Table 10-8.
All signals must be 50-Ω controlled impedance unless otherwise noted in Table 10-8.
|SIGNAL ON PIN||DIFFERENTIAL IMPEDANCE|
|DCKA_(P,N)||100 Ω ±10%|
|DCKB_(P,N)||100 Ω ±10%|
|USB_DAT_(P,N)||90 Ω ±10%|
|All other Differential Signals||100 Ω ±10%|
Table 10-9 lists the signals’ routing priority assignment.
|SIGNAL ON PIN||PRIORITY|
|DCKA_(P,N) SCA_(P,N) DDA_(P,N)_(15:00) DCKB_(P,N) SCB_(P,N) DDB_(P,N)_(15:00)||1 (1) (2) (3)|
|USB_(P,N) USB_DAT_(P,N)||2 (1)|
|P1(A,B,C)(9:2),P2(A,B,C)(9:2), P_CLK1, P_CLK2, P_CLK3, P_DATEN1, P_DATEN2, P1_VSYNC, P2_VSYNC, P1_HSYNC, P2_HSYNC||3 (1) (2) (3)|
|OCLKA, MOSCP||4 (4)|
