V C X O (VOLTAGE CONTROLLED CRYSTAL OSCILLATORS) “GS57” series 5x7 mm Wave Form: True Sine Wave MERCURY Since 1973 VCXO with true sine wave output has never been offered in such a small package in the industry – the GS57 (5x3.2x1.0mm). GS57 features low phase noise (<130 dBc / Hz at 1 KHz), low power (<20 m W) and wide supply voltage range. Applications include telecommunication systems and mobile phones. General Specifications TA=+25°C, VDD at specified voltage, load 10 K Ω // 10 pF Mercury Product Series Frequency Range Output Wave Form Input Voltage Range (VDD) Commercial Frequency Stability(1) (0°C to +70°C) Temperature code is ‘C” Industrial (extended) (-40°C to +85°C) Temperature code is ‘I” Voltage Control Characteristics Output Level Harmonic Distortion Output Load Current Consumption (typical) Start-up Time Voltage Control Range Frequency Deviation Range Linearity Slope Polarity Input Impedance Frequency Response 3 dB Modulation Band Width Phase Noise Aging Packaging GS57 PRELIMINARY 10 MHz ~40.0 MHz True Sine Wave VDD = +2.7 V D.C. min. +5.0 V D.
