Q30179FA
May 14, 2003

Background: Two LVDS line receivers were submitted for failure analysis along with their corresponding drivers. Testing showed the drivers were not failed and they will be addressed in a separate report.

Part Description: The 5962R9583402QXA is a low power, high speed CMOS low voltage differential signal (LVDS) quad line receiver provided in a 16-pin ceramic flatpack.

Conclusion: Failure of U62 was confirmed to be related to an ESD event. ESD testing of the IN(1-4)+ inputs on U59 revealed a relatively rugged ESD resistance. Permanent degradation of the monitored pin-to-pin characteristics was not noted until 5 kV assaults were imposed on the inputs. However, one of the inputs have manifested some degradation even after 1 kV zaps.

Three 5V, cold sparing, LVDS receivers were damaged during safe-to-mate testing.  The cause of failure was ESD.

LVDS Study HIGH-SPEED, LOW-POWER, EXCELLENT EMC: LVDS FOR ON-BOARD DATA HANDLING
Abstract
The capabilities of remote-sensing instrumentation are developing rapidly. As a consequence the data rates being handled on-board spacecraft are increasing.  LVDS (Low Voltage Differential Signaling) provides a means of sending data along a twisted pair cable at high speed, with low power and with excellent EMC performance. These features make LVDS ideal for satellite on-board data-handling applications.  This paper assesses the suitability of LVDS for space applications as part of a data-handling system based on IEEE 1355 comparing it against other types of line driver/receiver.  It explains how LVDS can be used together with IEEE 1355 to form the basis for a powerful on-board data handling system, which is capable of handling data from current and future, high data-rate instruments.
