Notes
1) Holdover and aging performance is after 7 days of power-on time.
2) Temperature stabilities apply to -20 to +70 ˚C modules. For other temperatures the temperature stability will
vary, however the hold over values over defined temperature ranges remain constant.
3) 24 hour average when locked to external 1PPS
4) The status locked indicator is intended to indicate when the module is fully locked to external 1 pps.
5) The Hardware OK indicator is intended to indicate when the module is operating properly without any failures
including hardware, software or parameter out of range, see protocol.
6) Open collector input bit.
7) If the minimum supply current is not exceeded, the Antenna Open Flag will be set. Over current will be set if
maximum is exceeded. Circuit has overcurrent protection.
8) The Rx pin is the serial interface input and the Tx pin is the serial interface output. The serial interface shall
operate at 9600 baud with eight (8) data bits, one (1) stop bit and no parity.
9) This holdover performance also applies to the temperature deviation over the entire operating range of -20 to
+70˚C.
