DCI debug interface
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
Chock chooses 3.3uH, >500mA
DCR<100m ohm.
Internal DC-DC 0.9v
output: Maximum 500mA
Signal GND and GND_DCDC must
be separated. They are
connected at a single point.
Close to
USB TYPE-C Conn.

FLIP:
USB Typc-C Orientation: 0=normal, 1=flipped
CC1 detection is normal or CC2 detection is
flipped
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.
