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 1.5Mb/s with the full
speed at 12Mb/s.
The PACUSB200 provides ESD protection, EMI
filtering and termination. It is ideal for protecting
vulnerable components in the workstations, notebooks
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 1.1
• 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
