MK2049-03

MK2049-02/03 Communications Clock PLLs Description The MK2049-02 and MK2049-03 are PhaseLocked Loop (PLL) based clock synthesizers that accept multiple input frequencies. With an 8 kHz clock input as a reference, the MK2049-02/03 generate T1, E1, T3, E3, ISDN, xDSL, and other communications frequencies. This allows for the generation of clocks frequency-locked and phaselocked to an 8 kHz backplane clock, simplifying clock synchronization in communications systems. The MK2049-02/03 can also accept a T1, E1, T3, or E3 input clock and provide the same output for loop timing. All outputs are frequency-locked together and to the input. These parts also have a jitter-attenuated buffer capability. In this mode, the MK2049-02/03 are ideal for filtering jitter from 27 MHz video clocks or other clocks with high jitter. ICS/MicroClock can customize these devices for many other different frequencies. Contact your ICS/MicroClock representative for more details. Features Packaged in 20 pin SOI...
