OEM7720 Strobe Specifications

Normally low.
A high output on this pin indicates that the receiver is in an error state. For information about the cause of the error, log the RXSTATUS log.

Input marks for which a pulse greater than 150 ns triggers certain logs to be generated. (Refer to the MARKxPOS and MARKxTIME logs and ONMARK trigger.) Polarity is configurable using the EVENTINCONTROL command.

Programmable variable frequency outputs ranging from 0 Hz to 50 MHz (refer to the EVENTOUTCONTROL command).

Indicates to the host system that the receiver is ready to receive commands.

This signal is not asserted while booting or during a reset.

If an error is detected during receiver operation (for example, an over temperature condition), the ERROR signal is asserted and the ME_RDY signal will normally remain asserted: commands can still be sent to the receiver under these conditions. At the time ERROR is asserted, POS_VALID signal is changed to not asserted. In the rare case of a fatal, unrecoverable error that leads to a reboot of the receiver, ME_RDY, ERROR and POS_VALID are all not asserted while the receiver restarts.

Indicates a valid GNSS position solution is available.

Reset signal input from external system; active low.

This pin must be held low for >20 µs while stable power is already applied, to reset the OEM7720 card.

It is recommended to hold the nRESET_IN pin low for a >150 ms when initially applying power to the card, giving the power supply time to stabilize before the card starts to boot.
