DESCRIPTION
The SY89327L is a fully differential, high-speed translator
optimized to accept any logic standard from single-ended
TTL/CMOS to differential LVDS, HSTL, or CML and translate
it to LVPECL. Translation is guaranteed for speeds up to
2.5Gbps (2.5GHz toggle frequency). The SY89327L does
not internally terminate its inputs because different interfacing
standards have different termination requirements.
The SY89327L is a member of Micrel’s Precision Edge^®
family of high-speed logic devices. This family features ultra-
small packaging, as well as high signal integrity and
operation at many different supply voltages.
All support documentation can be found on Micrel’s web
site at www.micrel.com.
