NCN1154
USB 2.0 High Speed, UART
and Audio Switch with
Negative Signal Capability
The NCN1154 is a DP3T switch for combined true−ground audio,
USB 2.0 high speed data, and UART applications. It allows portable
systems to use a single port to pass either high speed data or audio
signals from an external headset; the 3 channels being compliant to
USB 2.0, USB 1.1 and USB 1.0.
The switch is capable of passing signals with negative voltages as
low as 2 V below ground. The device features shunt resistors on the
audio ports. These resistors are switched in when the audio channel is
off and provide a safe path to ground for any charge that may build up
on the audio lines. This reduces Pop & Click noise in the audio system.
The NCN1154 is housed in a space−saving, ultra low profile
2.0x1.7x0.5mm, 12 pin UQFN package.
Features
• 3:1 High Speed Switch
• USB 2.0, USB 1.1 & USB 1.0 Capable on all Channels
• High Bandwidth of 820 MHz on D+/D−
• Capable of Passing Negative Swing Signals Down to −2 V on R/L
Channel
• 1.8 V Compatible Control Pins for 2.7 V v VCC v 4.2 V
• Audio Channel Shunt Resistors for Pop & Click Noise Reduction
• Ultra Low THD in Audio Mode: 0.01% into 16 W Load
• 5.25 V Tolerant Common Pins
• This is a Pb−Free Device
Typical Applications
• Micro or Mini USB Applications
• Shared High Speed Data or Audio on a Single Connector
• Mobile Phones
• Tablets
• Bar Code Scanners
• Portable Devices
