1PPS+TOD
Timing Relationship between 1PPS
and TOD
Transmission of a TOD message starts 1 ms
after the rising edge of 1PPS signal, and the
tramission is completed within 500 ms, as
shown in
Figure B-3. This TOD message
indicates the time of the current 1 PPS rising
edge, and is sent at a rate of once per second.
Rise Time -1PPS Pulse 50 ns
Pulse Width 50 ms < Pulse width < 200 ms
TOD Frame TOD messages use whole 8-bit bytes for
transmission, with check sum protection.
Message type and message ID are used to
clarify messages. Follows Big Endian
convention when a field is longer than one byte,
where bit 0 represents the least significant bit
(LSB), and bit 0 of each byte is transmitted first.
See
Figure B-4.
See
Table B-8 for TOD frame field
descriptions.
