MK2049-34
3.3 V Communications Clock PLL
MDS 2049-34 C
Integrated Circuit Systems, Inc. 525 Race Street San Jose CA 95126 (408)295-9800tel www.icst.com
1
Revision 121400
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
Accepts multiple inputs: 8 kHz backplane clock,
Loop Timing frequencies, or 10-36 MHz
Locks to 8 kHz ±100 ppm (External mode)
Buffer Mode allows jitter attenuation of
10–36 MHz input and x1/x0.5 or x2/x4 outputs
Exact internal ratios enable zero ppm error
Output clock rates include T1, E1, T3, E3, ISDN,
xDSL, and OC3 submultiples
See the MK2049-01, -02, and -03 for more
selections at VDD = 5 V
The MK2049-34 is a Phase-Locked Loop (PLL)
based clock synthesizer that accepts multiple input
frequencies. With an 8 kHz clock input as a
reference, the MK2049-34 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
MK2049-34 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 MK2049-34 is 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.
