3.3V, 2.5Gbps

ANY INPUT-to-LVPECL

DUAL TRANSLATOR

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.
