LYNX 53 Test board for automotive products
INTRODUCTION
Lyn53 is an electronic board used in high speed EOL testers when the impedance between pins of the DUT must be measured. It is base on ultrafast solid state relays (SSR). This way, minimum swtiching time and unlimited operations can be assured. Due to its internal design, each DUT pin can be addressed to any of the following contacts: • Backplane + • Backplane – • Bypass to a mirror connector.
FEATURES
• Board size: 295 x 100 mm.
• Rackable board for 19” subracks.
• Expandable when combined with Lynx backplanes.
• CAN and USB controlled.
• Compatible with Lynx Test Scheduler software.
• 72 solid state relays for addressing up to 24 pins.
• Maximum driving capability: 2A per relay.
• Main markets: automotive and industrial.
• Power supply ranging from +6.8V to +30V.

NOMENCLATURE
• DUT: Device Under Test.
• SSR: Solid Stat Relay.
• FID: Function Injection Device (device used to activate any DUT IO pin a certain signal with the objective to validate the associated funcion, e.g. ditigal input, analog input or power output).
• BKP: backplane.
APPLICATIONS
Lynx53 is the first interface between the DUT and the FID and allows an easy implementation of any of the following features:
• EOL fuctional testing for electronic modules.
• ICT testing with external DMM.
• Impedance testing beween DUT adjacent pins.
• Short circuit detection.
• Cables validaton.
• Signal injection integrity supervision.
