The C16 is a 10MHz high performance low phase noise clock generator. The C16's built-in crystal oscillator is a new SC-cut OCXO that has been customized from the top manufacturers in the crystal industry to ensure stable quality.. A true low jitter design with low near-end phase noise. Its measured performance is more than two orders of magnitude better than the traditional SPXO femtosecond crystal oscillator.. With six BNC interface outputs 33, it is divided into two output modes direct output and isolated output. The output waveform of the C16 is three or six square wave outputs, which is better for back-end device compatibility than sine wave output.. During the development process, we optimized the subjective and objective audio performance of the C16 specifically for the Gustard U16 and future audio digital source devices.. The C16 has better subjective and objective audio performance than the traditional SPXO femtosecond crystal oscillator, and the price is also relatively friendly. The C16 is not the most extreme performance design without considering cost. Instead, it uses a cost-effective OCXO to achieve a good balance between performance and price..
