PL-2301
USB TO USB BRIDGE CONTROLLER
OVERVIEW
The PL-2301 USB-to-USB Bridge Controller is a low-cost high-performance single chip solution that provides
bi-directional connectivity between any standard USB compliant host systems. Unlike previous file transfer
methods like serial cable, parallel cable and IrDA, the PL-2301 chip has a more advanced bus protocol and
operation system that offers much higher bandwidth and easier user interface.
The PL-2301 controller chip can be embedded into the link cable. Both sides of the cable function as an
upstream connector that could join a USB network such as the USB port of a PC or the downstream port of a
USB hub. Through switching and protocol adjustment in the controller chip, any two PCs or USB hosts can
communicate with each other while adopting maximum speed for bulk-type data formats. In addition, data
are allowed to flow in both directions simultaneously without compromising on performance. Both PCs can
control the device using standard USB command; the data flow is directed by a vendor-specific scheme.

As shown in the block diagram above, this ASIC
contains two USB units working independently.
Together with the two FIFOs and control logic in
between, they exchange data without blocking. The
entire clock oscillator, PLL, voltage regulators, USB
transceivers, and power-on reset circuits are
integrated on the chip. There is no glue logic
needed.
