TUSB6015ZQE

SLLS937

REVISION 1.4 SEPTEMBER 10, 2008

Digital Power Connections: VDD18, VDD15

The digital portion of the TUSB6015 has two power rails, 1.5V (VDD15) and 1.8V (VDD18). There is one digital

ground connection (VSS). Each supply is isolated from the others to provide noise isolation.

A combination of high-frequency capacitors near each terminal is suggested, such as paralleled 0.01uF and

0.001uF capacitors. A lower frequency 10uF filter capacitor is also recommended. All ground pins must connect

through a low impedance path to the circuit board ground plane. All grounds can be connected to each other.

• VDD15 (Digital Core Voltage 1.5V Supply) - (5) 0.1µf, (5) 0.001µf, (1) 10µf

• VDD18 (Digital IO Voltage 1.8V Supply) - (5) 0.1µf, (5) 0.001µf, (1) 10µf
