1.0 Features
2.0 Introduction
The PL-2301 operates as a bridge between two PCs (USB host) that are widely utilized in PC-to-PC
communication nowadays. With a more advanced bus protocol and operation system, this USB bridge
cable could offer much higher bandwidth and easier user interface.
This chip is embedded into a link cable. Either port is an upstream port that could join a USB network,
i.e. a PC’s USB connector or a USB hub’s downstream port. By means of switching and protocol
changing in the chip, any two PCs or USB hosts can communicate with each other. The bulk-type data
format is adopted for maximum speed. In addition, data are followed to flow in both directions
simultaneously without any performance compromising. The PCs can control the device using standard
USB command, while the data flow is directed by a vendor-specific scheme.
As shown in the block diagram next page, this ASIC contains two USB units working independently.
Together with the two FIFOs and control logics in between, they exchange data with no blocking. All
the clock oscillator, PLL, voltage regulators, USB transceivers, and power-on reset circuits are
integrated on chip. There is no glue logic needed. This chip is designed for handy cable utility.
