package SuperLiteв„ў DESCRIPTION
The SY55857L is a fully differential, high-speed dual
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 SY55857L does not internally terminate
its inputs, as different interfacing standards have different
termination requirements.
