Time of Validity (TOV) Output
Figure 18: TOV Timing Parameters
Parameter Description Value
T1 TOV high
Depends on MSYNC configuration;
MSYNC,IMU: high time is 10% of the
TOV period; for example: at default
rate of 1,000 Hz, the T1 high time will
be 100 µs for internal clock mode
MSYNC,EXT: high time is
approximately the same as the
external MSYNC signal active time
T2 TOV period
Depends on MSYNC configuration;
MSYNC,IMU: Period is determined
by the output data rate; for example,
at default data rate of 1,000 Hz, T2 =
1000 µs
MSYNC,EXT: period reflects the
external MSYNC signal
T3 Duration of serial
port output
Depends on output format and baud
rate; approximately equal to the
number of characters output
multiplied by the number of bits per
character (10) divided by the baud
rate; for example, format A at default
baud rate of 921600 Bd, T3 is
approx 390 µs
T4 Time between rising
edge of TOV-Out
and the end of data
transmission
<500 µs (at default format A and
baud rate of 921600 Bd)
T5 Time between start
of TOV and the start
of T3
Typically 30 to 100 µs
