LOW PHASE NOISE T1/E1 CLOCK GENERATOR DATASHEET MK1581-01 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 PHASE NOISE T1/E1 CLOCK GENERATOR

DATASHEET

MK1581-01

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.

Block Diagram
• Generates a T1 MHz or E1 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 V power supply
