MX102

The MX102 is a single-chip device to extract single periodic signals from very high random-noise environments. Using patented autocorrelation techniques the MX102 will enhance the input signal's signal-to-noise ratio by as much as 8.5dB and provide a digital output signal centered at four times (x4) the input frequency.

The amplitude of non-periodic components of the signal is substantially reduced. The patented autocorrelator compares the incoming signal to itself; the more elements of the waveform that are seen as periodic, the higher the energy at the microcircuit output.

The MX102 cascades two autocorrelators, each one improving the signal-to-noise ratio With a random noise input the output will swing rail-to-rail at random (peak-limited). The input/output signal delay is fixed by the choice of clock frequency and the length of the internal register. The MX102 will operate at supply voltages of between 2.5 volts and 5.5 volts and with Xtal/clock frequencies from 20kHz to 2.5MHz. Using various Xtal/clock inputs the device can be set to accept input signal frequencies, in bands, from 17.0Hz to 13.0kHz.

Two uncommitted clock outputs are available: one to supply a 'divided-down' Xtal/clock frequencies and the second is a buffered output for use in external and peripheral functions.

This MX102 is available in the following package styles: 16-pin SOIC (MX102DW) and 16-pin CDIP (MX102J).
