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.

7. No other delays than the RC network formed by the load resistance and the load capacitance of the switch are added on the bus. For a 10 pF
load, this delay is 5 ns which is much smaller than rise and fall time of typical driving systems. Propagation delays on the bus are determined
by the driving circuit on the driving side and its interactions with the load of the driven side.

DETAILED APPLICATION
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.
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

Figure 27. Schematic Example for USB 2.0, MHL, and UART Combination; NCN1188 Being Supplied by Protected
VBUS 5 V
In this second design proposal, as NCN1188 must be
active only when VBUS accessories are connected (USB
cable, UART cable and MHL cable), the device is supplied
from a protected VBUS 5 V. This design arrangement limits
the system’s overall quiescent current and saves battery life.
Figure 27 also pictures NCN1188 around a USB 3.0
Micro−B topology: USB 2.0, UART and MHL Video pairs
remain multiplexed with D− and D+ while the two USB 3.0
differential pairs are directly connected to the main
communication processor.
Pull−down resistors of 1 MW down to 100 kW can
optionally be added on the D− and D+ I/Os for preventing
eventual floating voltage situation on the NCN1188. This is
not systematically necessary and has to be considered in
regards to the application.
The flexibility of the NCN1188 offers many extra
application and design combinations.

PCB DESIGN PROCEDURE
• Make the signal traces as short as possible to reduce
Implementing a high speed device requires careful design
of signal traces to preserve signal integrity. The following
electrical layout guidelines are basic rules to follow when
designing boards capable of high speed transmission.
• The bypass capacitor must be placed as close as
possible to the VCC input pin for noise immunity.
• The PCB should be designed to comply with the
characteristic impedance requirements of MHL and
USB.
•
losses through the PCB. Furthermore, all corresponding
D+ / D− line segment pairs should be the same length.
The use of turns or bends to route these signals should
be avoided when possible. Use 45° bends instead of 90°
bends where bends are needed. The use of vias to route
these signals should be avoided when possible.
