APPLICATION INFORMATION

TIME MEASUREMENT SUPPORT

The ADATE207 contains support for time measurement

through an external time measurement unit (TMU) in the

following ways:

•

Connect the high comparator output of any channel to

TMU arm, TMU start, or TMU stop.

•

Connect the low comparator output of any channel to

TMU arm, TMU start, or TMU stop.

•

Tristate the TMU multiplexer outputs using an enable

control bit.

The time measurement unit select logic provides time and

frequency measurement capability from any digital pin high or

low comparator output. To accomplish this task, independent

multiplexers are employed for directing the high or low

comparator outputs of the digital pins to the (three) time

measurement unit signals, TMU_ARM, TMU_START, and

TMU_STOP. Off-chip control logic must select the appropriate

TMU bus output signal from the ADATE207 devices on the

board and direct its selection to the TMU.
