Hi there gentlemen,
Excuse in advance these newbie’s questions (I’m familiar with microcontrollers, but no with these ICs or sparkfun products or arduino…), and need your help with the following:
Is there any performance difference between the Si4703 and Si4735, significant enough, to make this receiver shield a more desirable choice?
Also, what is the purpose of the “HEX CONVERTER” shown in the schematic? Is not possible to interface the tuner directly from the host microcontroller?, or am I missing any other sort of translation in between?
Thank you in advance. I am starting a project related to RDS/RDBS and need to use one of these cards as a development start point for my project.
No public wish lists :(
