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 720p, 60fps and 1080i, 30fps. 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.

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 1080i, 30fps and 720p, 60fps • 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 28 and 29 detail two design examples with different switching combinations using NCN1188.

Schematic Example for USB 2.0, MHL, and UART Combination; NCN1188 Being Supplied by Protected VBUS 5 V 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. The flexibility of the NCN1188 offers many extra application and design combinations. 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 29 also pictures NCN1188 around a USB 3.0 http://onsemi.com 12 NCN1188 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 characteristic impedance of each High Speed USB segment must be 45 W. The characteristic impedance of each line is determined by (1) the distance between the signal trace and the inner layer ground plane of the PCB, as well as (2) the signal trace width. • losses through the PCB. Furthermore, all corresponding D+ / D− line segment pairs should be the same length. Route D+ / D− line segment pairs as close as possible for good common mode rejection. 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. http://onsemi.com 13 NCN1188 PACKAGE DIMENSIONS UQFN12 1.7x2.0, 0.4P CASE 523AE−01 ISSUE A D PIN 1 REFERENCE 2X 0.10 C 2X 0.10 C NOTES: 1.
