33、rough the connector via a USB interface. Three types of power shall be supported, low current (100 mA at 5 V), medium current (500 mA at 5 V) and high current (1.8 A at 5 V). A high current power supply allows a portable device to be charged at a higher rate than is possible using lower current USB
34、power. Note: When two portable devices are connected, power delivery shall be negotiated in accordance with the Universal Serial Bus Specification, USB On The Go Supplement, Revision 1.0a. The connector shall support high current power (1.8 A at 5 V) on separate power input pins (pins 6 and 15, with
35、 pins 7 and 16 grounds, respectively). There are two pins for 5 V high current power because the wire gauge of a single pin is not sufficient to carry 3.6 A. High current power in allows a portable device to be charged more quickly than with USB power. Note: CEA-2017-A changes the current amperes an
36、d may not be compatible with devices that are implemented using the ANSI/CEA-2017 specification. 4.2 Data Transfer Requirements The connector shall support data transfer to/from the portable device via a high speed (480 Mb/sec) USB 2.0 bus that complies with the Universal Serial Bus 2.0 Specificatio
37、n, Revision 2.0. The connector shall support data transfer to/from the portable device via a USB On-The-Go bus that complies with the Universal Serial Bus On-The-Go Supplement Revision 1.0a. USB On-The-Go 19CEA-2017-A 20functionality permits the portable device and the device to which it is connecte
38、d to negotiate which one will be the master and which will be the client. The connector shall support data transfer to/from the portable device via a super-speed USB 3.0 bus that complies with the Universal Serial Bus 3.0 Specification, Revision 1.0. The connector shall support digital communication
39、 with other devices for mutual device control using a single wire interface that complies with the High-Definition Multimedia Interface Specification Version 1.3A Specification, Supplement 1, Consumer Electronic Control (CEC). Data can be transferred over USB, DisplayPort, or both, depending on the
40、client device. USB will allow high-speed bidirectional transfer and is best suited for file management functions. It is also suited for playback of media using compressed data formats. DisplayPort is suited for the playback of non-compressed media, and provides content protection via HDCP. Low-speed
41、 bi-directional transfer is also possible over the DisplayPort AUX channel, which is useful for configuration and control information. See Section 4.5 for more detail on command and control mechanisms supported by this specification. 4.3 Analog Audio Line Output The connector shall support a stereo
42、line output signal coming from the portable device. Line level signals are defined in CEA-CPEB-6-A, Preferred Voltage and Impedance Values for the Interconnection of Audio Products. The portable device shall be assumed to have a high output impedance (greater than 1 k ohm). The audio output signal s
43、hall be assumed to be 500 mVrms nominal, 1.2 Vp maximum, with a frequency response of 20 Hz to 20 kHz. 4.4 Digital Video The connector shall support a digital video output stream that complies with the VESA DisplayPort Specification, version 1.1a. Two lanes of Main Link data are supported. CEA-2017-
