DIGITAL FILTER CHARACTERISTICS
3.
The equation for the group delay through the sample-rate converter is (56.581 / Fsi) + (55.658 / Fso). For example,
if the input sample rate is 192 kHz and the output sample rate is 96 kHz, the group delay through the sample-rate
converter is (56.581/192,000) + (55.658/96,000) =.875 milliseconds.
DC ELECTRICAL CHARACTERISTICS
(GND = 0 V; all voltages with respect to 0 V.)
4.
Power Down Mode is defined as RST = LOW with all clocks and data lines held static, except when a crystal is
attached across XTI-XTO, in which case the crystal will begin oscillating.
5.
Normal operation is defined as RST = HI.
