SUBJECT: Market research is being conducted to identify potential sources that may possess the expertise, capabilities, and experience to meet the requirements for qualification and production of the Interface Circuit Card Assembly (CCA), NSN: 5998-01-666-0874UC (PN: 4V10457-101A) / NSN: 5998-01-666-0853UC (PN: 4V10436-101A) and 5998-01-666-0840UC (PN: 4V10469-101A). ITEM DESCRIPTION: These items are used on the C-5 aircraft. The Interface Circuit Card Assembly (CCA) is contained in the Automated Flight Control System (AFCS) Panel, Communication/Navigation Panel (CNP), and Cursor Control Panel (CCP) Assemblies. The CCAs provide Aeronautical Radio Incorporated (ARINC) 429 communications with the aircraft bus. They consist of a line driver, two-line receivers, and interface circuits for the Integrated Panel. The line driver and line receivers interface the aircraft s ARINC 429 serial bus differential signals with the ARINC 429 communication interface on the Single Board Computer CCA. The Interface CCA also interfaces the Integrated Panel directly to Single Board Computer CCA.
