Description

The MK2049-35 is a Phase-Locked Loop (PLL) based clock synthesizer that accepts multiple input frequencies. With an 8 kHz clock input as a reference, the MK2049-35 generates T1, E1, T3, E3, OC3/3, Gigabit Ethernet, and other communications frequencies. This allows for the generation of clocks frequency-locked to an 8 kHz backplane clock, simplifying clock synchronization in communications systems.

Features

• 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 clock rates include T1, E1, T3, E3, and OC3 submultiples

• See the MK2049-01, -02, and -03 for more selections at VDD = 5 V, and the MK2049-34 for more selections at 3.3 V
