Internal 45K ohm pull-down.
Note:
Both SSTx and SSRx between USB host
and ANX7440 need AC capacitors.
USB host SSTx connects to ANX7440 SSRx.
USB host SSRx connects to ANX7440 SSTx.
The capacitors should be placed
near SSTx pin.
Note:
AC capacitors for DP
main link should be put
close to DP source

Compatible with 3.3V input.
Layout rules:
1. Place ANX7440/30/90/96 and USB Type-C/Type-A connector in an open area for
easier routing.
2. High-speed trace should be routed with high-priority.
3. If using internal DC/DC, create a dedicated DC/DC VGND
4. High-speed trace must keep distance from DC/DC and other noise source. RX
to TX spacing should be >20mils.
5. High-speed trace must be continuous and without stub, especially to RX
traces.
6. Ground void should be applied to wide pad along the high-speed traces.
7. ESD ground should be wide.
8. Every AVDD09 pin must have a 0.01uF decoupling capacitor that is very
close.
9. AVDD09 power delivery must be wide and away from noisy signal.
Note:
1. These capacitors are used to reduce the slew rate of AUX CH to
meet the DP V1.4 AUX CH requirement.
2. These capacitors are mandatory for HBR3 application, for HBR2
and lower, the caps are optional.
3. Both the upstream and downstream port need to add the
capacitor for HBR3 application.
