I'm sure some of you are more apt to answer, but I was wondering if someone could explain the functionality of 2 chips:
- MC98SR12 (Motorola)
- MAX2321 (Texas Instrument)
The MC98SR12 seems to be a UART type chip, but I couldn't find any specs on it. Anyone have a link?
The MAX2321 (on this zt-2 controller/display board) seems to take data in via Rin and send it back out to Rout. The specs made it seem like it was converting TTL/CMOS to Serial or Serial to TTL/CMOS. I don't understand the purpose of feeding it Serial data and then using its Serial data output, unless there's some sort of filter/cleaning of signal effect?
Help is appreciated.

The chips listed above are also on the PCB that feeds an Optrex/kyocera C-51505 LCD - Specs: http://www.kyocera-display.com/SiteImag ... JN_Eng.pdf
