Precision Edge 3.3V/5V 1.5Gbps DIFFERENTIAL SY89325V Micrel, Inc. Precision Edge CML/PECL/LVPECL-to-LVDS SY89325V TRANSLATOR FEATURES Guaranteed AC performance over temp and voltage: Precision Edge DC-to >1.5Gbps data rate throughput >750MHz clock f MAX DESCRIPTION <50ps within-device skew Ultra-low jitter design: The SY89325V is a fully differential, CML/PECL/LVPECL- <1ps random jitter RMS to-LVDS translator. It achieves LVDS signaling up to <10ps deterministic jitter PP 1.5Gbps and clock rates of 750MHz, depending of the <1ps cycle-to-cycle jitter RMS distance and the characteristics of the media and noise <10ps total jitter (clock) PP coupling sources. LVDS is intended to drive 50 impedance Accepts CML, PECL, LVPECL inputs transmission line media such as PCB traces, backplanes, or cables. 350mV LVDS output swing SY89325V inputs can be terminated with a single resistor Power supply 3.3V 10% or 5.0V 10% between the true and complement pins of the input. 40C to +85C temperature range The SY89325V is a member of Micrels Precision Edge Available in ultra-small (2mm 2mm) 8-pin MLF family of high-speed logic devices. This family features package ultra-small packaging, high signal integrity, and operation at many different supply voltages. For applications that require dual translators, consider the SY55855V.
