DESCRIPTION
The SY89325V is a fully differential, CML/PECL/LVPECL-
to-LVDS translator. It achieves LVDS signaling up to
1.5Gbps and clock rates of 750MHz, depending of the
distance and the characteristics of the media and noise
coupling sources. LVDS is intended to drive 50Ω impedance
transmission line media such as PCB traces, backplanes,
or cables.
SY89325V inputs can be terminated with a single resistor
between the true and complement pins of the input.
The SY89325V is a member of Micrel’s Precision Edge^®
family of high-speed logic devices. This family features
ultra-small packaging, high signal integrity, and operation at
many different supply voltages. For applications that require
dual translators, consider the SY55855V.
All support documentation can be found on Micrel’s web
