extracting a number from a string

Hi everyone,
I have a string as follow
ts1n65ulpa4096x16m16_130a_ss1p08v125c
i would like to extract 4096 and 16 from string and save it into two variable. but this string could also have the form
ts1n65ulpa32x16m16_130a_ss1p08v125c
therefore the number before "x" could be 2 or 3 digits. i use the following but this code is not able to extract more than one digit before "x"
echo "ts1n65ulpa4096x16_130a_ss1p08v125c" | sed -e 's/^[a-z0-9]*\([0-9][0-9]*x[0-9]*\).*/\1/'
the output is
6x16
which is missing 409 as the number before "x"
could anyone help me with this
