7.2.1 Design Requirements

For this design example, use the parameters shown in Table 7-1.

Table 7-1 Design Parameters
PARAMETER VALUE
Pre-channel A to B PCB trace length(1), LAB. 1 inches ≤ LAB ≤ 12 inches - LCD
Post-channel C to D PCB trace length(1), LCD. ≤ 4 inches
Minimum distance of the AC capacitors from TUSB1002A, LAC-CAP 0.25 inches
Maximum distance of ESD component from the USB receptacle, LESD 0.6 inches
Maximum distance of series resistor (RESD) from ESD component, LR_ESD. 0.25 inches
CAC-USB1 AC-coupling capacitor (75nF to 265nF) 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%) No used
Optional RESD (0Ω to 2.2Ω) 1Ω
VCC supply (3V to 3.6-V) 3.3V
Mode of Operation (Dual or Half Channel) MODE = F (Floating) for USB3.2 Dual Channel
Linear Range (900mV, 1000mV, or 1200 mV) 1200mV (CFG[2:1] pins floating)
DC Gain (-2, -1, 0, +1, +2) 0dB (CFG[2:1] pins floating)
(1) Maximum trace length assumes an insertion loss of 0.2dB/inch/GHz. If insertion loss is more than 0.2 dB/inch/GHz, then maximum trace length must be reduced accordingly.
