MK2049-34A - 3.3 Volt Communications Clock VCXO PLL

General Description

The MK2049-34A is a VCXO Phased Locked Loop (PLL) based clock synthesizer that accepts multiple input frequencies.

With an 8 kHz clock input as a reference, the MK2049-34A generates T1, E1, T3, E3, ISDN, xDSL, and other communications frequencies.

Key Features

  • Packaged in 20-pin SOIC 3.3 V + 5% operation Fixed I/O phase relationship on all selections 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 Timing frequencies, or 10 to 36 MHz.
  • Accepts multiple inputs: 8 kHz backplane clock, Loop.
  • Locks to 8 kHz + 100 ppm (External mode).
  • Buffer Mode allows jitter attenuation of 10 to 36 MH.

MK2049-34A 3.3 Volt Communications Clock VCXO PLL Description The MK2049-34A is a VCXO Phased Locked Loop (PLL) based clock synthesizer that accepts multiple input frequencies. With an 8 kHz clock input as a reference, the MK2049-34A generates T1, E1, T3, E3, ISDN, xDSL, and other communications frequencies. This allows for the generation of clocks frequency-locked and phase-locked to an 8 kHz backplane clock, simplifying clock synchronization in communications systems. The MK2409-34 can also accept a T1 or E1 input clock and provide the same output for loop timing. All outputs are frequency locked together and to the input. This part also has a jitter-attenuated Buffer capability.
