Using SX2 as the clock source.

Last Updated: June 09, 2011

Can the SX2 be used to clock an external device? If so, what are the steps?


Yes, the SX2 can be used to clock your external device. Here is how you set this up:

IFCONFIG bit 7 (IFCLKSRC) = 1 to tell the SX2 to use the internal clock

IFCONFIG bit 6 (3048MHZ) = 0 for 30MHz output or 1 for 48MHz output.

IFCONFIG bit 5 (IFCLKOE) = 1 to enable the IFCLK output pin.
