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
