Crystal for the SL811HS

Version 1
    Question: Can the SL811HS work off a 12 MHz crystal, and if so, how do you configure it?



    Yes, the SL811HS works off a 12 MHz crystal or a 48 MHz crystal. The CM pin is used to configure the clock. Tie it HIGH for 12 MHz and LOW for the 48 MHz. You must be aware of the errata on this part. Please note item 15, which states that the PLL used for 12 MHz operation, is susceptible to noise.
