8.2.1 Design Requirements

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

Table 8-1 Design Parameters
PARAMETER VALUE
Pre-channel A to B PCB trace length(1), LAB. 1 inches ≤ LAB ≤ 20 inches
Post-channel C to D PCB trace length(1), LCD. ≤ 6 inches
Minimum distance of the AC capacitors from TUSB522P, 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 (75 nF to 265 nF) 100 nF
CAC-USB2 AC-coupling capacitor (297 nF to 363 nF) Options:
  • RX1 or RX2 are DC-coupled to USB receptacle
  • 330 nF AC-couple with RRX resistor
Optional RRX resistor (220-kΩ ± 5%) Not used
Optional RESD (0-Ω to 2.2-Ω) Not used
VCC supply (3-V to 3.6-V) 3.3-V
EQ1 for RX1P/N (3, 6, or 9dB) 9 dB (EQ1 = High)
De-Emphasis 2 for TX2P/N (0, -3.5, and - 6.2 dB) -6.2 dB (OS2 = Low, DE2 = High)
EQ2 for RX2P/N (3, 6, or 9 dB) 6 dB (EQ2 = Floating)
De-Emphasis 1 for TX1P/N (0, -3.5, and -6.2 dB) -3.5 dB (OS1 = Low, DE1 = Floating)
Output Swing 1 (0.9 or 1.1 Vppd) 900 mV (OS1 = Low)
Output Swing 2 (0.9 or 1.1 Vppd) 900 mV (OS2 = Low)
(1) Maximum trace length assumes an insertion loss of 0.2 dB/inch/GHz. If insertion loss is more than 0.2 dB/inch/GHz, then maximum trace length must be reduced accordingly.
