Evo Clock

Precision clock generator

Word clock and master clock generation; lowest phase-noise, high precision, custom made temperature-compensated oscillators; dedicated matched line master clock output for hiFace Evo; matched line option for word clock output; word clock frequency up to 384kHz, plus 5.6448/6.144MHz and 11.2896/12.288MHz “super clock”; ultra-low noise regulators.


Evo Clock is a cost-effective, high-performance clock generator based on extremely low phase noise, high precision TCXO’s, custom made for M2Tech. Two outputs are available: one master clock dedicated to hiFace Evo, capable of 22.5792MHz or 24.576MHz (depending on settings) and delivering 3.3Vpp on 75 Ohms matched line, and a general purpose word clock output with selectable output frequency up to 384kHz, with the option for “super clocks” 128x and 256x. The latter has a line matching option and can deliver 3.3Vpp on both high impedance and 75 Ohms loads. Ultra-low noise regulators allow for a very clean supply for both oscillators and the conditioning logic, leading to fully exploiting the oscillators performance.
