Description
The MK1581-01 provides synchronization and timing
control for T1 and E1 based network access or multitrunk
telecommunication systems. The device accepts an 8 kHz
frame clock input and uses an on-chip VCXO to produce a
synchronized low phase noise clock output.
This monolithic IC, combined with an external inexpensive
quartz crystal, can be used to replace a more costly hybrid
VCXO retiming module. Through selection of external loop
filter components values, the device can be tailored to meet
the system’s clock jitter attenuation requirements. Low-pass
jitter attenuation characteristics in the Hz range are
possible.
Features
Generates a T1 (1.544 MHz) or E1 (2.048 MHz) output
clock from an 8kHz frame clock input
Configurable jitter attenuation characteristics, excellent
for use as a Stratum source de-jitter circuit
VCXO-based clock generation ensures very low jitter and
phase noise generation
Output clock is phase and frequency locked to the input
reference clock
+115ppm minimum crystal frequency pullability range,
using recommended crystal
Industrial temperature range
Low power CMOS technology
16 pin TSSOP package
Single 3.3 V power supply
