9.

Typical base band jitter in accordance with AES-12id-2006 section 3.4.2. Measurements are Time In-
terval Error (TIE) taken with 3rd order 100 Hz to 40 kHz band-pass filter. Measured with Sample Rate
= 48 kHz.

10. OLRCK must remain high for at least 1 OSCLK period and at most 255 OSCLK periods in TDM Mode.

11. In TDM formatted master mode, the TDM_IN pin is not supported.

12. In TDM formatted master mode, the OSCLK frequency is fixed at 256*OLRCK.
