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. Basic configuration is determined by a Mode/Frequency Selection Table. Loo.
• Packaged in 20-pin SOIC
• 3.3 V + 5% operation
• Meets the TR62411, ETS300 011, and GR-1244
specification for MTIE, Pull-in/Hold-in Range, Phase Transients, and Jitter Generation for Stratum 3, 4, and 4E
• Accepts multiple inputs: 8 kHz backplane clock, or 10 to
50 MHz
• Locks to 8 kHz + 100 ppm (External mode)
• Buffer Mode allows jitter attenuation of 10 - 50 MHz input
and x1 / x0.5 or x1 / x2 outputs
• Exact internal ratios enable zero ppm error
• Output rates include T1, E1, T3, E3, and OC3
submultiples
• Pb (lead) free package
