SY58038U中文资料Multiplexers数据手册Microchip规格书

描述 Description

The SY58038U is a low-jitter, low-skew, high-speed 8:1 multiplexer with a 1:2 differential fanout buffer optimized for precision telecom and enterprise server distribution applications. The SY58038U distributes clock frequencies from DC to 3.5GHz, and data rates to 4.5Gpbs guaranteed over temperature and voltage.The SY58038U differential input includes Micrel's unique, 3-pin input termination architecture that directly interfaces to any differential signal (AC- or DC-coupled) as small as 100mV without any level shifting or termination resistor networks in the signal path. The outputs are 800mV, 100K compatible LVPECL with extremely fast rise/fall times guaranteed to be less than 100ps.The SY58038U features a patented isolation design that significantly improves channel-to-channel crosstalk performance. The SY58038U operates from a 2.5V ±5% or 3.3V ±10% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. The SY58038U is part of Micrel's high-speed, Precision Edge®product line.
