2. DESIGN HIGHLIGHT
2.1 ADAPTIVE FIFO MEMORY CACHE ARCHITECTURE
Adaptive FIFO technology is used to transfer the audio data input to the high-speed RAM
buffer, and, by using the high stability active crystal clock signals generated from within,
extract the audio data from the high-speed RAM and converts these data to I2S protocol,
then, transmit the I2S data to the R2R DAC for DA conversion.
This FIFO is literally jitter free. It eliminates the possible jitter caused by the upstream
source, cable, or the digital receiver chip in the DAC. Let’s put it this way, the number of
jitter in Terminator DAC can only be caused by the quality of FIFO active crystal. Terminator
crystals are high end CRYSTEK FEMTO 9 series clock, and powered by LDO regulator, the
jitter is so small that it can be neglected.
2.2 I2S INPUT
Terminator i2s DAC works slave mode, the source i2s shall provide the necessary MCLK to
work with the DAC. The i2s is not an industrial standard, DENAFRIPS cannot guarantee the
compatibility with other i2s devices.
2.3 All New USB Audio Solution
The Terminator is equipped with the proprietary USB Audio Solution via STM32F446
Advanced AMR Based MCU, with DENAFRIPS redesigned and optimized circuitry, allow the
DAC to be used as high-end DAC with computers / streamers. It supports 24bit/1536kHz
PCM data stream, and native decoding of DSD up to DSD1024. It comes with licensed
Thesycon USB Driver for Windows Platform.
NOTE: The USB Module is designed to trigger on only when USB Input is selected. This is
intended design to reduce inputs cross interference for best sound reproduction.
2.4 Proprietary SPDIF DIGITAL AUDIO RECEIVER
The SPDIF Coaxial, TOSLink, AES/EBU input support up to 24bit/192kHz digital audio format.
The Terminator abandon the use of Digital Audio Receiver chip. The digital data is decoded
by the on-board FPGA (Field Programmable Gate Array), shorten the signal path and
eliminated the undesired coloration.
2.5 NOS/OS
Fancy of NOS/OS selection to change the sound signature of the DAC? The Terminator allow
the user to change the sampling mode on the fly. NOS, as the name suggested, does not do
Over Sampling of the digital input stream. The sampling rate of the digital input signal
remain untouched, and it is converted to analogue output signal right away.
