NCN1188
3:1 High Speed USB Switch
with Audio and MHL
Capability
The NCN1188 allows portable systems to share a single USB 2.0 or
3.0 receptacle to transmit and receive paired signals from three
separate locations. All of the three differential channels are compliant
to High Speed USB 2.0, Full Speed USB 1.1, Low Speed USB 1.0 and
any generic UART protocol. The two dedicated high speed data paths
also support Mobile High Definition Link (MHL) video up to
resolutions of 1080i (2.25 Gbps) and 1080p (3 Gbps in Packed Pixel
mode). The multi−purpose audio path is capable of passing signals
with negative voltages as low as 2 V below ground and features shunt
resistors to reduce Pop and Click noise in the audio system. The
NCN1188 is housed in a space saving, ultra low profile 2.0 x 1.7 x
0.5 mm, 12 pins UQFN package.
Features
• High Bandwidth of 1.8 GHz
• VCC Operating Range from 2.7 V to 5.5 V
• VIS Signal from 0 V to 3.7 V for Data Transfer
• VIS Signal from −2 V to 2 V for Stereo Headphone Connection
• Audio Shunt resistor for Pop & Click Noise Reduction
• VIO Control Pins Compatible to 1.8V Interfaces
• Low Power Consumption of 23 mA
• Small UQFN 2.0 x 1.7 x 0.5 mm Package
• These Devices are Pb−Free and are RoHS Compliant
Typical Applications
• USB 2.0 / 3.0 Micro−B Applications
• USB to HDMI Video Interfaces via MHL
• Features Phones and Smart Phones
• Digital Cameras
• Handset Media Players

DETAILED APPLICATION
The NCN1188 voltage range and high bandwidth
performance permits switching between audio, video and
data signals on a portable device. It allows D+ and D− data
pins of a single USB connector to be used for many different
functions as pictured by Figure 1:
• USB 2.0 data transfer with backward compatibility to
USB 1.1 and USB 1.0
• MHL high definition video transfer up to 3 Gbps for
1080p resolutions
• Audio headset with negative voltage capability to
connect true ground audio amplifier
• UART to address programming and testing in factory
• Any other analog or digital data sources within the
recommended operating conditions
Figures 26 and 27 detail two design examples with
different switching combinations using NCN1188.
In the first example shown in Figure 26, the device is
directly supplied from a single Li−Ion battery, typically
from 3.0 V to 4.2 V. The NCN1188 switch connects a 5−pin
micro−USB connector to a Communication Processor, an
MHL Application Processor, and the Audio Management IC
headphone amplifier. Each function is active pending on
power management IC accessory detection to control IN1
and IN2. This decision is usually made on the D−, D+, and
ID pins to detect and differentiate accessory types such as
USB cable, USB to HDMI MHL cable and micro−USB
stereo headset.
For solutions related to portable devices accessory
detection, contact your ON Semiconductor Field
Applications Engineer.
The USB 3.0 Micro−B receptacle may be considered a
combination of the USB 2.0 Micro−B interface and USB 3.0
SuperSpeed contacts and maintains backward compatibility
with USB 2.0 Micro−B plugs. As a consequence, the
NCN1188’s USB 2.0 capability is fully compatible to the
USB 3.0 Micro−B receptacle, as well as USB 2.0
accessories.
