COS ALGORITHM, BUFFER and RE-CLOCKING
COS's proprietary algorithm with a linear-phase delay FIR filter can up-sample original data to 176.4K or 192K. D10 stores digital data in a one-second buffer before converting to analog signals, under the coordination of a crystal oscillator with a jitter precision less than 1ps and a dedicated re-clocking circuitry.
