Chapter 1 Introduction The translator/oscillator buffer evaluation module (EVM) allows evaluation of the SN65LVDS16/17/18/19/20 and SN65LVP16/17/18/19/20 repeaters/translators/oscillators. This user’s guide provides a brief overview of the EVM, operation instructions, and output results.

Observing an EVM U1 Output 1.3 Observing an EVM U1 Output The outputs are available at J1 and J2 for direct connection to oscilloscope inputs. Matched length cables must be used when connecting the EVM to a scope to avoid inducing skew between the noninverting (+) and inverting (−) outputs. The three power jacks (P2, P3, and P4) are used to provide power and a ground reference for the EVM. The power connections to the EVM determine the common-mode load to the device.
