Symbol names ending with underscore N, for example, NAME_N, represent active LOW signals.
All ground pins should normally be connected to a common ground plane.
I = input only; O = output only; I/O = digital input/output; OD = open-drain output; AI/O = analog
input/output; AI = analog input; P = power; G = ground supply; NC = not connected.

Description
digital supply voltage; 1.65 V to 3.6 V; connect a 100 nF
decoupling capacitor; see
host controller DMA request acknowledgment; when not in
use, connect to V
input, 3.3 V tolerant
connect to V
core power output (1.8 V); internal 1.8 V for the digital core;
used for decoupling; connect a 100 nF capacitor; for details
on additional capacitor placement, see
host controller suspend and wake-up; 3-state suspend output
(active LOW) and wake-up input circuits are connected
together
connect to V
output pad, open-drain, 4 mA output drive, 3.3 V tolerant
pull up to V
core ground
external power-up reset; active LOW; when reset is asserted,
it is expected that bus signals are idle, that is, not toggling
input, 3.3 V tolerant
Remark: During reset, ensure that all the input pins to the
SAF1760 are not toggling and are in their inactive states.
analog ground
connect a 220 nF capacitor between this pin and pin 125
connect a 220 nF capacitor between this pin and pin 124
connect to 3.3 V
port 1 analog (5 V input) and digital overcurrent input; if not
used, connect to V
input, 5 V tolerant
port 2 analog (5 V input) and digital overcurrent input; if not
used, connect to V
input, 5 V tolerant
