3.3 Volt Communications Clock PLL
Description
The MK2049-36 is a Phased Locked Loop (PLL) based
clock synthesizer that accepts multiple input
frequencies. With an 8 kHz clock input as a reference,
the MK2049-36 generates T1, E1, T3, E3, OC3 and
other communications frequencies. This allows for the
generation of clocks frequency-locked to an 8 kHz
backplane clock, simplifying clock synchronization in
communications systems.
This part also has a jitter-attenuated Buffer capability.
In this mode, the MK2049-36 is ideal for filtering jitter
from clocks with high jitter.
ICS can customize these devices for many other
different frequencies. Contact your ICS representative
for more details.
Features
Packaged in 20 pin SOIC
3.3 V + 5% operation
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 10
to 50 MHz
Locks to 8 kHz + 100 ppm (External mode)
Buffer Mode allows jitter attenuation of 10 - 50 MHz
input and x1/x0.5 or x1/x2 outputs
Exact internal ratios enable zero ppm error
Output clock rates include T1, E1, T3, E3, and OC3
submultiples
