Introduction

The AX7MCF4-187.5000C is an oscillator designed for pin frequency application field. The oscillator provides a stable output frequency of 187.5000C. It is designed to replace a wide range of oscillators, such as crystal, ECL, LVPECL and PECL. The device is optimized for low jitter, low noise, and high performance. This make is suitable for various down-hole logging, remote location monitoring, radar, cable TV and satellite communication systems.

Working Principle

The AX7MCF4-187.5000C oscillator uses the phase-locked loop (PLL) architecture to achieve highly stable frequency output. It uses an oscillator core and is completely temperature-compensated. The signal input is a differential frequency generator (DFG), which is used to adjust the output frequency over a wide range in small increments. The core resonator produces a signal, which is compared against the reference frequency. The output of the loop filter is the result of the comparison; it is a control voltage which is sent out to the VCO. The VCO\'s output is filtered and fed back into the PLL loop.

The output of the PLL is a sinusoid that is in phase with the reference frequency. The output frequency of the oscillator is determined by the frequency of the DFG and the loop filter bandwidth. The oscillator core is designed to reject any external noise sources and to minimize jitter. The device is also immune to environmental temperature changes, as it has temperature compensation circuitry.

Features and Benefits

The AX7MCF4-187.5000C oscillator is designed for high performance, low jitter, and low noise operation. It features an embedded temperature compensation circuitry, which ensures that the output frequency remains stable even when subjected to extreme environmental conditions.
