REV H 051310
Description
The MK2059-01 is a VCXO (Voltage Controlled Crystal
Oscillator) based clock generator that produces common
telecommunications reference frequencies. The output
clock is phase locked to an 8kHz (frame rate) input
reference clock. The MK2059-01 also provides jitter
attenuation. Included in the selection of output frequencies
are these common system clocks:
1.544 MHz (T1)
2.048 (E1)
19.44 MHz (OC-3)
16.384 MHz (8x E1)
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, the PLL loop bandwidth and damping
factor can be tailored to meet input clock jitter attenuation
requirements. A loop bandwidth down to the Hz range is
possible
Features
Generates T1, E1, OC-3 and other common telecom
clock frequencies from an 8kHz frame clock
Configurable jitter attenuation characteristics, excellent
for use as a Stratum source de-jitter circuit
2:1 Input MUX for input reference clocks
VCXO-based clock generation offers very low jitter and
phase noise generation
Output clock is phase and frequency locked to the
selected input reference clock
Fixed input to output phase relationship (except for 1.544
MHz and 2.048 MHz output selections)
+115ppm minimum crystal frequency pullability range,
using recommended crystal
Industrial temperature range
Low power CMOS technology
20 pin SOIC package
Single 3.3V power supply
Pb (lead) free package
