Strictly speaking, the clock driving NADAC D’s 1-bit DAC comes from the [MF Advanced Clock Data Recovery System] , not directly from the NADAC C.

The NADAC C’s 10 MHz master clock serves as the reference foundation. However, we still need the clock recovery module because it performs essential tasks like removing residual jitter, aligning timing between clock domains, and generating the exact multi-channel clock signals required by the 1-bit architecture. So rather than being redundant, the clock recovery system is a necessary final stage that ensures absolute precision.
