MK2058-01SITR集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

描述 Description

The MK2058-01 is a VCXO (Voltage Controlled Crystal Oscillator) based clock jitter attenuator designed for system clock distribution applications. This monolithic IC, combined with an external inexpensive quartz crystal, can be used to replace a more costly hybrid VCXO retiming module. The device accepts and outputs the same clock frequency in selectable ranges covering 4kHz to 27MHz. A dual input mux is also provided.

特性 Features

• Excellent jitter attenuation for telecom clocks

• Also serves as a general purpose clock jitter attenuator for distributed system clocks and recovered data or video clocks

• 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
