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.

Features

• Generates T1, E1, OC-3 and other common telecom clock frequencies from an 8kHz frame clock

• Configurable jitter attenuation characterisitics, 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

• +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
