MK2049-45 Overview
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.
Key Features
- Packaged in 20 pin SOIC
- 3.3 V + 5% operation
- 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
- Available in Pb (lead) free package
- Not recommended for new designs. Use the MK2049-45A
