Problems solved by technology

[0003] The pin layout of the existing popular mobile phone platforms is limited, and the interface definitions are also changed accordingly. Most of them only support the MIPI interface, while omitting the traditional parallel interface. Or the MIPI interface and the parallel port multiplex the same physical interface, but you can only choose one or the other. have both

Abstract

The present invention discloses a time division multiplexing device of a MIPI interface and a parallel port, a method thereof and a mobile terminal. The time division multiplexing device comprises a plurality of one-in-two-out switches. The input end of each of the one-in-two-out switches is connected to the baseband chip of a mobile terminal, and the output end is connected to the MIPI interface and parallel port of the mobile terminal. The time division multiplexing of the MIPI interface and the parallel port is realized, and thus the MIPI interface and the parallel port are supported by the mobile terminal at the same time.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a device, method and mobile terminal for time-division multiplexing of MIPI interface and parallel port. Background technique [0002] As customers have higher and higher requirements for mobile phone camera pixels and transmission speed, traditional parallel port transmission is increasingly challenged. Improving the output clock of parallel port transmission is one way, but it will make the EMC design of the system more and more difficult, and increasing the number of bits of the transmission line does not conform to the trend of miniaturization. Compared with the parallel port, modules using the MIPI (Mobile Industry Processor Interface, MIPI) interface have the advantages of fast speed, large amount of transmitted data, low power consumption, and good anti-interference, and are more and more favored by customers and are growing rapidly. [0003] The pin layout of the e...
