Test Equipment


I took the Frequency Counter listing off the main Test Equipment Manufacturers page.
The new page is located on the Frequency Counter Manufacturers page.

DIMM Form Factors


This page provides the physical sizes of DIMM cards. The Memory Module Physical Sizes page really just accounts for DDR II or DDR III memory modules.

Older DIMM formats and SIMM formats are listed under the main Memory Module pinout page. SIMM cards are obsolete.

The top right of the Memory Module Form Factor page also provides links to all the other DIMM related pages;

FCIP Protocol Description


I also added a page to cover Fibre Channel over IP, or FCIP.

FCIP enable the transmission of Fibre Channel (FC) information by tunneling data between storage area network (SAN) facilities over IP networks

However; as of today the page is only a place holder, until I have time to update the information.

iSCSI Description

I added a page to cover iSCSI, or Internet SCSI.

iSCSI is really a protocol and not a physical bus, but I added under both the hardware buses and the protocol sections. iSCSI provides a mean of sending SCSI commands over an IP network.

The original SCSI interface is a physical parallel interface bus. The latest version, although not back-ward compatible is called Serial SCSI or SAS 'Serial Attached SCSI.

ST-Bus

I added a page to cover the Serial Telcom Bus, or ST-Bus.

A serial Bus standard from Zarlink. The page only has a few paragraphs just now, but I do provide a link to Zarlink specification in pdf format. I'm giving just enough data to tell what type of serial interface it is until I have time to get back and enhance the page

Analog Audio ICs


I split the analog IC Manufacturers page into three sections;
General Analog ICs, the main page;
IC Codec Manufacturers,
Modem IC Manufacturers.

Each of the sub-pages were derived from the main Audio IC page. All the IC manufactures links seemed to still be working.

A Codec is similar to a ADC, A-to-D converters are listed on the A to D and D to A Converter ICs page.

Annular Ring

I noticed the Blog feed stats was showing a few hits for these search terms;
Annular Ring: 50 hits
Annular Rings: 5 hits
Minimum Annular Ring: 4 hits

So I added this page to cover the Minimum Annular Ring definition. Than a second page to cover odd shaped PCB Pads.
