The MK2049-45SITR is a dual Phase-Locked Loop (PLL) clock generator designed for communications applications. It operates at a supply voltage of 3.3 V and is packaged in a 20-pin SOIC format. This device features a VCXO-based PLL that utilizes an external pullable crystal to track signal wander and attenuate input jitter, making it suitable for high-frequency clock filtering. The MK2049-45 supports multiple input frequencies, accepting an 8 kHz backplane clock or a 10 to 50 MHz input. It can generate output frequencies from a selection table, including T1, E1, T3, E3, and OC3 submultiples. The device allows for dynamic switching between these outputs while maintaining low jitter and phase noise characteristics. Engineers can configure the loop bandwidth and damping factor through external loop filter components. The MK2049-45 meets various telecommunications specifications, including TR62411 and ETS300 011, ensuring reliability in communication systems. However, it is noted that this part is not recommended for new designs, with the MK2049-45A suggested as an alternative.
