SY55857L Datasheet | Micrel Semiconductor

Micrel, Inc. 3.3V, 2.5Gbps ANY INPUT-to-LVPECL DUAL TRANSLATOR Super Lite™ Super LSYit5e5™857L SY55857L Features s Input accepts virtually all logic standards: - Single-ended: SSTL, TTL, CMOS - Differential: LVDS, HSTL, CML s Guaranteed AC parameters over temperature: - f MAX > 2.5Gbps (2.5GHz toggle) - tr / tf < 200ps - Within-device skew < 50ps - Propagation delay < 400ps s Low power: 46m W/channel (typ) s 3.0V to 3.6V power supply s 100K LVPECL outputs s Flow-through pinout and fully differential design s Two channels in a 10-pin (3mm × 3mm) MSOP package Super Lite™ 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.
