DIGITAL / ANALOGUE ISOLATION

​

The TERMINATOR-PLUS Digital Processing Board and R-2R ladder network arrays are completely isolated. The two boards are physically linked by the OCXO module. The physical isolation yields even lowered noise-floor and achieved higher signal to noise ratio.

OVER CONTROLLED CRYSTALS – OCXO

​

“The BEST clocks are the clocks inside the DAC”.

​The TERMINATOR-PLUS is equipped with two OCXO at audio frequencies 45.1548Mhz, 49.152Mhz. Encapsulated in a metal casing, located at the centre of the DAC, these OCXO are specially designed for high-end audio applications with ultra-low phase-noise and ultra-accuracy. The OCXO are powered by the complete redesigned power supply circuitry (encapsulated, shielded, underneath the main boards), supplying constant current to the OCXO. These power reserves ensure linearity and stability of the OCXO.

ADAPTIVE FIFO BUFFER RECLOCKING

​

The DENAFRIPS approach to address the jitters issue by the FIFO BUFFER RECLOCKING. The adaptive FIFO buffer store the digital audio data in the memory. These data are read from the memory using the ultra-low phase noise, ultra-accuracy OCXO, located right in the DAC.

​

The data bits are converted to analogue signal by the true balanced R-2R ladder network arrays. The linearity of the conversion is guaranteed by the high-precision thin film resistors, with low thermal effect temperature coefficient of the low 10/15ppm.
