Ext Clock/Ref for two-channel 89610A

I am using Agilent 89600A VSA in a two-channel 89610A configuration... The source of Ext Clock/Ref for this system is a 10MHZ clock from a Xilinx Virtex-4 fpga's digital I/O which supports LVCMOS standard output...

Ext Clock/Ref on VSA can accept ECL or TTL standard inputs according to E1438 User Guide... I have read on the internet that the output voltage specification of LVCMOS is compatible with input voltage specification of TTL... Do you think it is safe to connect fpga's I/O (LVCMOS) directly to VSA Ext Clock (TTL) for my application?
