SD394EVK - Evaluation Board for LMH0394 Cable Equalizer


Order now


The SD394EVK is an evaluation board designed to demonstrate the performance and capabilities of the LMH0394 3G HD/SD SDI Low Power Extended Reach Adaptive Cable Equalizer.

The board accepts 75Ω input signals conforming to the SMPTE 424M, SMPTE 292M, or SMPTE 259M standards. The LMH0394 will restore the input signal after it has been attenuated by coaxial cable. The LMH0394 differential output is provided via two 50Ω SMA connectors. Jumpers on the board can be configured for evaluation of LMH0394 features such as auto sleep, carrier detect, mute, bypass, and SPI mode / pin mode select.
