The  x163 seems to be in better supply than the '161.

For example: < http://www.nxp.com/documents/data_sheet/74LVC163.pdf >
At 3.0 - 3.6V  150 MHz guaranteed, 200 MHz typ.

I have done a fanout board for the Xilinx Coolrunner XC2C64 to 100 mil 
square pads.
The small chip in the Background is the core voltage regulator, The plug 
fits to
the Xilinx USB configuration cable. Enough to create 1pps from 100 MHz.

The other small boards are 100 MHz Crystek CVHD-950 locked to 10 MHz 
using LVC163

Doubler 100 MHz ---> 200 MHz  13dBm in -> 13 dBm out using 2*BF862 
push/push grounded gate

Doubler 200 MHz -> 400 MHz  13 dBm in 13 dBm out, HSMS-282F, SAW Filter 
on 400 MHz, ERA-4 amplifier

All are week-enders, Layout printed on Laser printer to foil, 
presensitized FR-4 0.5mm from Bungard, home etched.
The bottom side ist ground only.
I can use these snippets in my Altium Designer to combine them to larger 
projects; the modules keep
their layout and need only to be handled as a block. I have collected 
quite a block library over the years. :-)
