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).

Autocorrelating Signal Processor 4 MX102 2. Signal List Packages DW/J 1 Signal Name Signal In Type input The inverting input to the analog amplifier/comparator. Used with the Signal Bias pin; external coupling components are required. See Figure 2 The output of the analogue amplifier/comparator. Do not load this pin with peripheral circuitry; there is no drive capacity for off-chip signaling. The feedback resistor should be not less than 200k. See Figure 2. Positive supply rail. A single, stable power supply is required. Note that this device has two VDD pins; this input is positioned to prevent cross-talk, either or both may be connected to the host circuit's supply line. Do not attempt to draw current from either VDD pin. Buffered inverter oscillator digital output. May be used as test point to align clock frequency or to drive other circuitry. The output of the on-chip clock oscillator inverter. The input to the on-chip clock oscillator inverter; this may be a Xtal, resonator or clock pulse input. The selection of this frequency will affect the operational input signal bandwidth (and output frequency) of this device; refer to Table 4. Note that the choice of VDD will determine the maximum Xtal/clock frequency and hence the maximum useable signal input frequency. Operation of this microcircuit without an active Xtal or clock input may cause device damage. A clock pulse input is fed directly into this pin; Xtal/clock components are not required. See Table 2. Negative Supply A squarewave output clock signal at the rate of Clock/6; provided for peripheral and test purposes. (fOUT = 4 x fSIGNAL IN). The auto-correlated output signal at four times (x 4) the input signal (see Figure 3). There is a time delay between input and output signals (see Specifications). Positive supply rail. A single, stable power supply is required. Note that this device has two VDD pins; either or both may be connected to the host circuit's supply line. Do not attempt to draw current from either VDD pin. The choice of VDD will determine the maximum Xtal/clock frequency and hence the maximum useable signal input frequency (see Figure 4). 2, 7, 10, 12, 14, 15 N/C No internal connection.

CML Microcircuits COMMUNICATION SEMICONDUCTORS CML Product Data In the process of creating a more global image, the three standard product semiconductor companies of CML Microsystems Plc (Consumer Microcircuits Limited (UK), MX-COM, Inc (USA) and CML Microcircuits (Singapore) Pte Ltd) have undergone name changes and, whilst maintaining their separate new names (CML Microcircuits (UK) Ltd, CML Microcircuits (USA) Inc and CML Microcircuits (Singapore) Pte Ltd), now operate under the single title CML Microcircuits. These companies are all 100% owned operating companies of the CML Microsystems Plc Group and these changes are purely changes of name and do not change any underlying legal entities and hence will have no effect on any agreements or contacts currently in force. CML Microcircuits Product Prefix Codes Until the latter part of 1996, the differentiator between products manufactured and sold from MXCOM, Inc. and Consumer Microcircuits Limited were denoted by the prefixes MX and FX respectively. These products use the same silicon etc. and today still carry the same prefixes. In the latter part of 1996, both companies adopted the common prefix: CMX. This notification is relevant product information to which it is attached. CML Microcircuits (USA) [formerly MX-COM, Inc.] Product Textual Marking On CML Microcircuits (USA) products, the `MX-COM' textual logo is being replaced by a `CML' textual logo.
