MK2049-45, MK2049-45A, CLOCK PLL
The MK2049-45A is a dual Phase-Locked Loop (PLL) device which can provide frequency synthesis and jitter attenuation.
The first PLL is VCXO based and uses a pullable crystal to track signal wander and attenuate input jitter.
The second PLL is a translator for frequency multiplication.
