MK3754ATR中文资料ICST数据手册PDF规格书

描述 Description

The MK3754 is ICS/Microclock’s lowest cost, low jitter, high performance 3.3 Volt VCXO and PLL clock synthesizer designed to replace expensive 54 MHz VCXOs. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3.3 V input voltage to vary the output clocks by ±100 ppm. Using ICS/Microclock’s patented VCXO and analog/digital Phase-Locked Loop (PLL) techniques, the device uses an inexpensive external 13.5 MHz pullable crystal input to produce a 54 MHz output clock.

特性 Features

• Packaged in 8 pin SOIC

• 3.3 V only operating voltage

• Uses an inexpensive 13.500 MHz external crystal

• On-chip VCXO (patented) with pull range of 200ppm (minimum)

• VCXO tuning voltage of 0 to 3.3 V

• 12mA output drive capability at TTL levels

• Advanced, low power, sub-micron CMOS process

• The A version is the latest, manufactured in a smaller geometry process. The MK3754A gives a wider pull range than the MK3754S, and so is recommended for all new designs, and cost reductions of existing designs.
