If you want a product that ships on time, you dont buy Maxim ;-)

A 14bit DAC can be had for about 2USD at 1000pcs. A TCXO costs
in the order of 1USD at 1000pcs. A simple XO goes for less than 0.1$.

I guestimate that a GPS receiver like a u-blox LEA has a BOM cost
of less than 10$. Adding a 2$ component will seriously hurt the
ability of the CEO to buy a new Porsche with his next bonus. ;-)
