Digital I/O—External Clock (XTALI)
(Guaranteed performance across worst-case supply voltage and temperature range, unless otherwise specified.)
Crystal Requirements (XTALI/XTALO)
(Guaranteed performance across worst-case supply voltage and temperature range, unless otherwise specified.)
Serial Peripheral Interface (SPI) Bus Specications
(Guaranteed performance across worst-case supply voltage and temperature range, unless otherwise specified.)
Note 14: User can configure the SC2200 to accept the following external clock frequencies: 10, 13, 15.36, 19.2, 20, 26 and
30.72MHz. External clock frequency other than 20MHz requires programming through the SPI bus. Refer to the
Programming Guide and Hardware Design Guide for more information.
