Product Description
The USB is a four wire system utilizing a two wire twisted pair for transferring data, and two lines to supply power and ground
connection to hubs and devices. The USB allows for two modes of signaling. The low speed mode is defined at 1.5Mbs with
the full speed at 12Mbs.
The PACUSB200 provides ESD protection, EMI filtering and termination. It is ideal for protecting vulnerable components in the
Workstation, Notebook and Desktop computers as well as in hubs. This device supports two downstream ports. California
Micro Devices also offers a complementary device to provide filtering and ESD protection for the upstream port. The
PACUSB200 has the following characteristics:
Compatible with Universal Serial Bus specification 1.0.
Capacity to protect both the system and device from external ESD pulses up to 6KV per the HBM.
Suppress EMI/RFI noise on high speed data lines.
