Iterra iT4050D
The iT4050D is a wideband LVDS-to-SCFL level translator fabricated using 0.1μm HBT GaAs technology. It is based on ECL topology to guarantee high-speed operation. The two translators are fully independent, allowing power consumption to be optimized according to the application.DESCRIPTION
The device can translate NRZ streams with data rate up to 3.125 Gb/s or clock signals with a frequency up to 3.125 GHz. The inputs and outputs of the iT4050D are DC coupled. At the input side, internal 100-ohm resistors between the two differential lines avoid the need for external impedance matching terminations. The input levels are fully compliant with LVDS specifications. The iT4050D uses SCFL output levels and allows either single ended or differential data output. The excellent rise and fall time and the good quality of the eye diagram at all data rates up to 3.125 Gb/s makes the iT4050D suitable for interfacing a generic LVDS output buffer with all iTerra SCFL parts.FEATURES
