External Components
MK1707D requires minimum number external components proper operation.
layout Recommendations
optimum device performance lowest output phase noise, following guidelines should observed. 0.01µF decoupling capacitor should mounted component side board close possible. vias should used between decoupling capacitor pin. trace should kept short possible, should trace ground via. minimize EMI, series termination resistor needed) should placed close clock output. optimum layout with components same side board, minimizing vias through other signal layers. Other signal traces should routed away from MK1707D. This includes signal traces just underneath device, layers adjacent ground plane layer used device.
Decoupling Capacitor
decoupling capacitor 0.01µF must connected between pins close these pins possible. optimum device performance, decoupling capacitor should mounted component side PCB. Avoid vias decoupling circuit.
Series Termination Resistor
When trace between clock output load over inch, series termination should used. series terminate trace commonly used trace impedance), place resistor series with clock line, close clock output possible. nominal impedance clock output
Select Operation
select pins 2-level, meaning they have three separate states make selections shown table page
