8.2.1 Design Requirements

For this design example, use the parameters provided in Table 8-1.

Table 8-1 Design Parameters
PARAMETER(1) VALUE
Redriver to USB3 Hub maximum PCB trace length, XAB 8 inches
Redriver to DP RX maximum PCB trace length, XEF 6 inches
Redriver to Type-C connector maximum PCB trace length, XCD 2 inches
Maximum distance of ESD component from the USB receptacle, LESD 1.0 inches
Maximum distance of series resistor (RESD) from ESD component, LR_ESD. 0.25 inches
CAC-USB1 AC-coupling capacitor (75nF to 265nF) 100nF or 220nF
CAC-USB2 AC-coupling capacitor (297nF to 363nF) Options:
  • RX1 and RX2 are DC-coupled to USB receptacle
  • 330nF AC-couple with RRX resistor
Optional RRX resistor (220kΩ ± 5%) 220kΩ ± 5%
Optional RESD (0Ω to 2.2Ω) 1Ω
VCC supply (3V to 3.6V) 3.3V
I2C Mode or GPIO Mode I2C Mode. (I2C_EN pin != "0")
1.8V or 3.3V I2C Interface 3.3V I2C. Pullup the I2C_EN pin to 3.3V with a 1K ohm resistor. CTL1, EQ[1:0], SSEQ[1:0], and DPEQ[1:0] pin unconnected.
EQ setting for DisplayPort Lanes EQ Setting # 5 (Register 0x0A[4] = 1'b1, 0x10 = 0x55; 0x11 = 0x55)
EQ setting for Downstream USB Data Path EQ Setting # 6 (Register 0x0A[4] = 1'b1, 0x20 = 0x66)
EQ setting for Upstream USB Data Path EQ Setting # 6 (Register 0x0A[4] = 1'b1, 0x21 = 0x08)
(1) Maximum trace length assumes an insertion loss of 0.2dB/inch/GHz. If insertion loss is more than 0.2dB/inch/GHz, then maximum trace length must be reduced accordingly.
