Synchronization
| Multi-stage, auto-ranging PLL per Path | |
| Ultra-high-precision mode | (+/- 0.15%) |
| Jitter rejection corner frequency | ~80Hz |
| Jitter rejection slope | 60dB / decade |
| Jitter attenuation | >60dB above 700Hz |
| High-precision mode | (+/- 6.0%) |
| Internal | 32, 44.1, 48, 88.2, 96, 176.4, 192 kHz +/-25ppm |
| Each path can be separately synchronized. Path sampling rate can be frequency-locked to a different reference frequency, for example: 96kHz path locked to 48kHz Worldclock. | |
