About this file
This is a Statement of Work (SOW) from NASA's Lyndon B. Johnson Space Center for procurement of Synchronous Serial Interface (SSI) Master Module Boards for rapid prototype test hardware. The SOW requires 8 units of catalog assembly part number DNR-SL-514, with specific technical requirements including 4-port synchronous serial communications, industry standard SSI master/slave functionality, clock rates up to 1.3 MHz, and custom programmable capability enhanced from 32-bit to 128-bit CLOCK/DATA FRAME. Additional specifications include 350 Vrms channel-to-channel & channel-to-chassis isolation and fully differential inputs/outputs at RS-422 logic levels. The components should be manufactured according to vendors' own COTS specifications, with the full assembly to be delivered to NASA Johnson Space Center's Mechanical Design and Analysis Branch, with delivery fees and estimated lead time to be included in the cost estimate.

STATEMENT OF WORK
Procurement of Enhancement and Manufacturing of Synchronous Serial Interface (SSI) Master Module Board(s) for rapid prototype Test Hardware
Sourcing capability is being procured for a Commercial Off the Shelf/COTS solution for a Synchronous Serial Interface (SSI) Master Module which is required for this NASA application. The parts should be manufactured according to the following details:
1. QTY 8 of catalog assembly part number DNR-SL-514 with a technical description of:
• 4-Port Synchronous Serial Communications
• Industry standard SSI master or slave functionality
• Clock rates up to 1.3 MHz
• Custom programmable up to 128-bit CLOCK/DATA FRAME
a. Note: Enhancement is from 32-bit to 128-bit.
• 350 Vrms channel-to-channel & channel-to-chassis isolation
• Fully differential inputs/outputs at RS-422 logic levels
2. All piece parts in the assembly should be manufactured or procured according to vendors own
COTS specifications/drawings.
3. While the assembly is composed of multiple piece parts, the end-product should be QTY 8 of the fully assembled component, per Vendors own part number – DNR-SL-514
The full assembly should be delivered to NASA Johnson Space Center Mechanical Design and Analysis
Branch/ES5 c/o Monty Carroll/ES5/(218)483-8452(d)(713)818-9282(m) and delivery fees should be part of the cost estimate along with an estimated lead time.
