sequence of samples locked to an arbitrary
reference, such as a broadcast transport stream

series resistor is recommended to reduce ringing.
AI_SCK is limited to 25 MHz. The sample rate of
valid samples embedded is variable. If used as a

AI_SCK is an input. AI_SCK receives the serial
bit clock from the external A/D subsystem. This
clock is treated as fully asynchronous to the

interface timing master, AI_SCK is an output.
AI_SCK drives the serial clock for the external A/
D subsystem. The frequency is a programmable
integral divide of the AI_OSCLK frequency.
