Basic Electronics and Tutorials

National Semiconductor was an American semiconductor manufacturer, that specialized in analog devices and subsystems, formerly headquartered in Santa Clara, California, USA. The products of National Semiconductor included power management circuits, display drivers, audio and operational amplifiers, communication interface products and data conversion solutions.

Wiki of National Semiconductor

National's key markets included wireless handsets, displays and a variety of broad electronics markets, including medical, automotive, industrial, and test and measurement applications.

On September 23, 2011, the company formally became part of Texas Instruments as the "Silicon Valley" division.

The LMH0356 Serial Digital Interface (SDI) reclocker is designed to recover a clean clock from a serial digital video signal which may be contaminated by jitter and to resynchronize the input video data to the recovered clean clock. The LMH0356 SDI reclocker accepts signals conforming to standards SMPTE 259M (C), SMPTE 292M, and SMPTE 424M.

These helped me build Intelligent Instruments in the 80s. Intersil was with GE earlier, innovators of   advanced CMOS before anybody else. They made the smartest chips when the Microprocessors were being examined Skeptically by engineers. (At that time Microprocessors needed many support chips and consumed huge power only later CMOS uC came).

Today i found out that another company of that time called Datel is back, it was first a part of GE like Intersil then went to Murata now after decades it is back home.

"Datel was established in 1970 and has been a long time leader in providing high precision data acquisition components, including data converters, power supplies, DC-DC converters, and digital panel meters. "
