Description

The MK2049-45 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. Basic configuration is determined by a Mode/Frequency Selection Table. Loop bandwidth and damping factor are programmable via external loop filter component selection. Buffer Mode accepts a 10 to 50MHz input and will provide a jitter attenuated output at 0.5 x ICLK, 1 x ICLK or 2 x ICLK. In this mode the MK2049-45 is ideal for filtering jitter from high frequency clocks. In External Mode, ICLK accepts an 8 kHz clock and will produce output frequencies from a table of common communications clock rates, CLK and CLK/2. This allows for the generation of clocks frequency-locked to an 8 kHz backplane clock, simplifying clock synchronization in communications systems. The MK2049-45 can be dynamically switched between T1, E1, T3, E3 outputs with the same 24.576 MHz crystal. ICS can customize these devices for many other different frequencies.
