Denafrips Terminator Plus DAC

2.SOPHISTICATED DESIGN, 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.
OVEN-CONTROLLED CRYSTAL OSCILLATORS – OCXO
The BEST clocks are the clocks inside the DAC.

The TERMINATOR-PLUS is equipped with dual OCXO operating at audio frequencies 45.1584Mhz, 49.152Mhz. Encapsulated in a metal casing, located at the center of the DAC, these OCXO are specially designed for high-end audio applications with ultra-low phase-noise and ultra-accuracy. The dual OCXO are powered by the complete redesigned power supply circuitry (encapsulated, shielded, underneath the main boards), supplying constant current to the OCXO. The adequate 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.



3.MASTER CLOCK ECO-SYSTEM
With the GAIA and AVATAR matching clock input, the digital front-end can now be synchronized with the CLOCK-OUT feature of the Terminator-Plus DAC.
