New Embedded USB probe from LeCroy for Inter-Chip and portable electronic device

LeCroy has made available of a low-cost probe for monitoring embedded USB 2.0 and inter-chip links within a multi-chip PCB assembly. The probe allows accurate capture of both standard and reduced voltage inter-chip USB protocol data and operates with the entire line of LeCroy USB analyzers, and suitable for portable electronics devices.

The Inter-Chip USB (IC-USB) specification defines a standard methodology for using USB in chip-to-chip communications, used as a replacement for i2C, the IC-USB allows to control data transfers between endpoint functions within an embedded device. In many cases, developers can leverage on-board embedded USB host or hub logic that is frequently present on portable consumer electronics devices.

LeCroy's embedded probe supports tapping these chip-to-chip links using low or full speed Inter-chip signaling at all defined IC-USB voltages. These embedded USB links do not generally use standard USB connectors. These devices embed USB physical links directly in the printed circuit board. The embedded probe provides a flying lead tap that can be connected directly to Inter-chip probe points using solder-in resistor connections. The probe can also be used to tap USB 2.0 links at standard 5-volt signal levels.

"IC-USB is increasingly being used to provide faster transfers for digital images or audio content within a mutli-chip portable device - such as a smart phone", stated Mickey Romm, Director of Product Development at LeCroy. "The inter-chip probe and our USBMobile T2 analyzer provide everything the embedded developer needs to verify these transceiver-less USB applications".
