package
The TQ8710 is a 1 input to 10 output buffer utilizing a 3.3V single power supply
and differential LVPECL/ECL input and output signal levels. The device is well
suited to high speed clock fanout applications where low skew and low additive
jitter are important considerations.
Applications
• Clock distribution to 1.5 GHz
• Data distribution to 2.7 Gb/S
• CMOS backplane buffering
• 50 Backplane driver
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 50 transmission lines, including
stripline, microstrip, coax structures and cables.
• 50 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.
