The device is well suited to high speed clock fanout applications where low skew and low additive jitter are important considerations. The device is capable of either direct coupled LVPECL/ECL interfacing or AC coupled operation. Minimum differential signal sensitivity of 200mVp-p allows the device to be AC coupled to most types of balanced high speed signalling levels. The device is suitable for driving 50W transmission lines, including stripline, microstrip, coax structures and cables. Applications • Clock distribution to 1.5 GHz • Data distribution to 2.7 Gb/S • CMOS backplane buffering • 50W Backplane driver • 50W Coax driver The device is packaged in a plastic TSSOP package which addresses thermal management through the use of a metal tab on the bottom center of the package. This tab is utilized as a required Vdd power supply connection as well as a thermal path to the host circuit board.
