Packaged in 20 pin SOIC
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
Loop Timing frequencies
Locks to 8 kHz ±100 ppm (External mode)
Exact internal ratios eliminate the need for external
dividers
Zero ppm synthesis error in all output clocks.
Output clock rates include T1, E1, T3, E3, and
OC3÷8
5 V ±5% operation
Offered in Commercial and Industrial temperature
versions
The MK2049 is a Phase-Locked Loop (PLL) based
clock synthesizer, which accepts an 8 kHz clock input
as a reference and generates T1, E1, T3, E3, and OC3
frequencies. The device 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. This allows for the generation of locked
clocks to an 8 kHz backplane clock, simplifying clock
distribution in communications systems.
ICS can customize this device for many other different
frequencies. Contact your ICS representative for more
details.
For a fixed input-output phase relationship, refer to the
MK2049-02, -03, or -3x. The MK2049-3x are 3.3 V
devices.
