FCT806 Clock Driver

Hello SI engineers,
I am having problems with an IDT 49FCT806BT inverting clock driver, 0.5
micron CMOS technology. I measured the rise time on this device to be
800ps, and this is causing excessive reflections and false clocking. Does
anyone know of a vendor who makes a pin compatible FCT806 clock driver,
SSOP package with slew rate control or guaranteed rising edges around 1.5ns
or longer? I don't need subnanosecond edges in my system, the frequency is
below 50MHz.
Thanks in advance for any advice.
Hope to see many of you at Design Supercon next week in Santa Clara.

Regards,

Fabrizio Zanella
