      That then begs the question, what is the difference in pricing between
      CMOS and LVDS for the quantities being asked for?

        Here's the schematic for an Si570 PCB I'm working on:

        http://www.leonheller.com/Si570/Si570.pdf

        The board includes a PIC16LF88 MCU, with a 3.3V LDO regulator, and has
        connectors for a rotary encoder and two pushbuttons. It's mostly
        surface-mount, and being single-sided will be easy to make at home. Size is
        1.325" x 2.15".

        Is that a ICSP connector to program the chip? Or is it some other standard.
        Yes, it's for an ICD 2 debugger/programmer.
