Additional preview pages of the MK2049-36 datasheet.

The MK2049-36 is a Phase-Locked Loop (PLL) based clock synthesizer that accepts multiple input frequencies.

With an 8 kHz clock input as a reference, the MK2049-36 generates T1, E1, T3, E3, OC3/3, Gigabit Ethernet, and other communications frequencies.

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 err.
