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. http://onsemi.com MARKING DIAGRAM 1 AC = Specific Device Code M = Date Code G = Pb−Free 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 APPLICATION DIAGRAM NCN1154 COM+ Rx COM− Tx R Micro or Mini USB Applications Shared High Speed Data or Audio on a Single Connector Mobile Phones Tablets Bar Code Scanners Portable Devices IN1, IN2 USB/ UART USB/ UART USB/ UART/ Audio L Typical Applications • • • • • • D+ D− USB Connector • • • • ACM G UQFN12 MU SUFFIX CASE 523AE From Baseband ORDERING INFORMATION Device NCN1154MUTAG Package Shipping† UQFN12 3000 / Tape & Reel (Pb−Free) †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specification Brochure, BRD8011/D. © Semiconductor Components Industries, LLC, 2011 May, 2011 − Rev. 3 1 Publication Order Number: NCN1154/D NCN1154 VCC D+ COM+ D− TX L RX L COM− IN1 D+ 1 Tx 2 10 COM+ VCC 3 9 GND Rx 4 8 COM− D− 5 7 IN2 12 11 R IN1 Control Logic 6 R GND (Top View) IN2 Figure 1.
