MCCI, HSIC, and MIPI in the News

Developments in interconnect, or chip-to-chip, communication technologies are a crucial part of high-speed mobile device development. In its discussion of SMSC's patented Inter-Chip Connectivity (ICC) technology, a recent article in the EE Times mentioned MCCI's "protocol analyzer" and HSIC verification tool, which we call the MCCI Catena® 1910 HSIC. ICC is a chip-to-chip interface that uses USB data transfer protocols over a maximum bus length of 10 cm. ICC was standardized by the USB-IF in 2010. The Catena 1910 captures, traces, and analyzes data transferred over this interface.

Another recent press release discussed the MIPI Alliance's High Speed Interface (HSI) specification, which provides for an improved on-chip-interconnect solution intended to compete with SMSC's ICC. If you're going to work with MIPI, take a look at the Catena 1910 MIPI. The 1910 MIPI can act both as a passive receiver and as a transmitter/verifier.

NCM Means High Performance Networking

NCM (Network Control Model) is one of the USB Implementers Forum's major stories for 2011.  Here are some detailed responses from MCCI CEO Terry Moore to a few questions about the NCM device class specification:

Q: Can you please give us a quick, high-level explanation of what the NCM specification is?

A: The Network Control Model (NCM) specification is a high-performance standard for connecting networking devices to PCs using USB.  Although it was designed specifically to support the needs of new 4G network standards (such as LTE and WiMax), it has substantial benefits when used for any kind of network traffic.

Q: What are the key features and benefits of the NCM specification?

NCM has two key features: First, it allows multiple Ethernet frames to be encapsulated in a single USB transfer...
