X2
XO
Crystal connection. Connect to a pullable crystal of 17.664 MHz or 24.576 MHz.
External Components
The MK3732-08 requires a minimum number of external components for proper operation. Decoupling capacitors of
0.01F should be connected between VDD and GND pins 3 and 7, pins 4 and 8, and pins 5 and 9, as close to the
MK3732-08 as possible. A series termination resistor of 33
may be used for each clock output. The input crystal
must be connected as close to the chip as possible. The input crystal should be a fundamental mode, parallel
resonant, pullable, AT cut.
