The Teledyne LeCroy HDO4K-USB2-HSICBUS D High-Speed Inter-Chip (HSIC) technology communicates between microchips in an embedded subsystem and leverages the traditional host-device topology of USB, utilizing a large amount of existing USB code. This makes HSIC extremely lucrative in areas demanding fast time-to-market solutions, such as the mobile industry including both smart phones and tablets. The USB2-HSICbus D option extracts transaction-level data from a USB2-HSIC signal to show significant transitions in the signal.

The USB 2.0 HSIC link and data layer decode information is annotated on the physical layer waveform. Various sections of the protocol are color coded to make it easy to isolate various opcodes and frames. Decode annotation information condenses or expands depending on the timebase/ zoom ratio setting. HSIC decode annotation helps in isolating problems that cannot be completely attributed to physical layer issues. The Data and Strobe Offset setting on the oscilloscope menu enables the user to identify the correct level for which the receiving end will be able to understand the traffic. Protosync (separate option) takes the HSIC decode annotation to an even higher level by displaying the USB transaction in the CATC® protocol view on the scope screen or on a separate monitor. With Physical Layer waveforms, USB 2.0 HSIC decode annotation and Protosync, the test engineer has the ability to view the entire hierarchy of the USB 2.0 HSIC traffic in a single instrument, a unique feature unmatched in the industry.

Long oscilloscope acquisition memory provides long capture times of USB 2.0 HSIC traffic. Any of the USB 2.0 packets, events or errors can be searched for on this decoded trace. In addition, the table data may be exported as a CSV file

The USB 2.0 HSIC decode option is available on a wide range of oscilloscope models with real-time bandwidths from 1 GHz to 45 GHz.
