VOLT COMMUNICATIONS CLOCK VCXO PLL DATASHEET MK2049-34A 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. In this mode, the MK2049-34A is ideal for filtering jitter from 27 MHz video clocks or other clocks with high jitter. IDT can customize these devices for many other different frequencies.
