In the Space business, several manufacturers from the USA and Europe have under their portfolio LVDS microcircuits. Taking into account such wide offer, it is valuable to know the similarities and differences between the options available.
Among the manufacturers that have Quad LVDS Drivers and Receivers in their catalog, the following ones will be considered in this post:
- ST Microelectronics (European)
- LVDS Driver and Receiver manufactured by ST are radiation hardened, MIL-PRF-38535 qualified up to quality level QML V and without any export restriction. Included in the same drawing (5962-98651 for drivers and 5962-98652 for receivers), are available cost-effective versions with relaxed electrical parameters but also radiation hardened and without any export restriction.
- 3D+ (European)
- These parts, not formally qualified, are offered under Space screening and lot qualification, with radiation data available and no export restriction.
- Space IC (European)
- Parts manufactured by Space IC are not formally qualified but are radiation tested in terms of TID and SEE. As well as screened and tested as per the ESCC system. As occurs in the case of other European manufacturers, they have no export restriction.
- Cobham Microelectronic Solutions (USA)
- Being radiation hardened up to 1 Mrad (Si), these LVDS are MIL-PRF-38535 qualified to QML V level against the drawing 5962-98651 for drivers and 5962-98652 for receivers. In terms of export classification, they are classified with ECCN 9A515.e.2
- Texas Instruments (USA)
- These parts are listed in QPL-38535, qualified to QML V level against the drawing 5962-97621 for drivers and 5962-97622 for receivers, but not radiation hardened although radiation reports are available to support the radiation analysis. They have no export restriction.
The only highest quality level and packaged products (SOP-16 for 3D+ and FP-16 for the rest) are included herein. For all of them, the supply voltage is [3, 3.6] V and the Operating Temperature Range (Ta) is [-55, +125] ºC, except for SPACE IC parts, which is [-40, +125] ºC
