Teledyne LeCroy Embedded USB Probe (USB-FE02-V01-X)

Inter-Chip USB (IC-USB) specification defines a standard methodology for using USB in chip-tochip communications. It is used in the embedded systems market as a replacement for i2C to control data transfers between endpoint functions within an embedded device. IC-USB allows vendors to leverage onboard embedded USB host logic to enable faster chip-tochip communications using USB physical links within a multi-chip PCB assembly.

Teledyne LeCroy’s embedded probe supports tapping these chip-to-chip links using low or full speed Inter-chip signals at all defined IC-USB voltages. The probe can also be used to tap USB 2.0 links at standard 3.3 volt signal levels.

The embedded probe utilizes a 4-wire header plug that can be attached as a solder down tap or as flying lead connection attached directly to header pins on the DUT. Probing techniques above can be used for both USB 2.0 compliant electrical links or low/full speed Inter-chip links. The USB protocol traffic can be monitored (via the D+/Dwires) by attaching the probe to the “A” port of a Teledyne LeCroy USB analyzer.
