PACUSB100 CALIFORNIA MICRO DEVICES USB UPSTREAM PORT FILTER WITH ESD PROTECTION Features Provides EMI/RFI filtering Bi-Directional ESD protection Circuitry for optimum system protection Very small package USB 1.1 compliant Applications Keyboard, mouse, game peripherals Speakers Scanners/printers Monitors Modems 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 PACUSB100 provides ESD protection with EMI filtering and termination. It is ideal for protecting vulnerable components in devices like keyboard, mouse, scanner/printer, etc. The PACUSB100 also supports upstream ports. California Micro Devices also offers a complementary device (PACUSB200) to provide filtering and ESD protection for downstream ports. The PACUSB100 has the following characteristics: Compatible with Universal Serial Bus specification 1.0. Protects both the system and device from external ESD pulses up to 6KV per the Human Body Model. Suppresses EMI/RFI noise on high speed data lines.

R1 = 33 Ohm R2 = 15K Ohm R3 = 1.5K Ohm2 C1 = 47 pF Note 2: Full speed and low speed devices are differentiated by the position of the pull-up (1.5K) resistor on the downstream end of the cable. Full speed devices are terminated with pull-up on the D+ line. Low speed devices are terminated with the pull-up on the D- line. (c)2000 California Micro Devices Corp.
