Sure:  just pick one out of a catalog!  AT&T, Valprey-Fisher, Austron,
Bliley, Colorado Crystal Corp, Conner-Winfield Corp, Croven Crystals,
CTS Corp, and probably a dozen others make "canned" crystal oscillators.
Look in the EEM Master catalog, available in your local (large) library.
Attach +5 at one end, ground at the other, and get TTL levels out, to
the precision you pay for.  The "standard" ones (100 ppm or so) go for
roughly $5 a pop.  2.048-Mhz is one of those "standard" values that
phone companies like to use, so you probably will be able to get what
you want off the shelf!  VXCO's are also avaliable.  Have fun!
