package Precision EdgeВ® 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. …
