u-blox F9 high accuracy timing module

Data sheet

Abstract

This data sheet describes the ZED-F9T timing module with multi-band

GNSS receiver and nanosecond-level timing accuracy. ZED-F9T meets

the most stringent 5G timing requirements, is ideal for global deployment

due to GPS, BeiDou, Galileo, and GLONASS reception, and is unaﬀected by

ionospheric errors. The module provides diﬀerential timing mode for highly

accurate local timing and built-in security for highest robustness against

malicious attacks.

ZED-F9T - Data sheet 1 Functional description 1.1 Overview The ZED-F9T is a multi-band GNSS module oﬀering 5 ns (1-sigma) timing accuracy with unparalleled low power consumption. The ZED-F9T incorporates the u-blox F9 multi-band platform in a small surface-mount device with a form factor of 22 x 17 mm. 1.2 Performance Parameter Speciﬁcation Receiver type Multi-band GNSS receiver for timing applications 1 Absolute timing mode Accuracy of time pulse signal 5 ns 2.

ZED-F9T - Data sheet In order to achieve the maximum timing accuracy, it is recommended to measure the propagation delay of the entire signal path from the antenna to the receiver's time pulse output, and then compensate for this delay using the CFG-TP conﬁguration items.

ZED-F9T - Data sheet QZSS can be enabled only if GPS operation is also conﬁgured. 1.4.2 Satellite based augmentation system (SBAS) The ZED-F9T timing module supports SBAS (including WAAS in the US, EGNOS in Europe, MSAS in Japan and GAGAN in India) to deliver improved location accuracy within the regions covered. However, the additional inter-standard time calibration step used during SBAS reception results in degraded time accuracy overall. SBAS reception is disabled by default in ZED-F9T. 1.4.

Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only. Operation of the device at these or at any other conditions above those given below is not implied. Exposure to limiting values for extended periods may aﬀect device reliability.

ZED-F9T - Data sheet 5 Communications interfaces There are several communications interfaces including UART, SPI, I2C12 and USB. All the inputs have internal pull-up resistors in normal operation and can be left open if not used. All the PIOs are supplied by VCC, therefore all the voltage levels of the PIO pins are related to VCC supply voltage. 5.1 UART interface The UART interfaces support conﬁgurable baud rates. See the ZED-F9T Integration manual [1]. Hardware ﬂow control is not supported.

ZED-F9T - Data sheet Figure 3: ZED-F9T timing module SPI speciﬁcation mode 1: CPHA=0 SCK = 5.33 MHz Timings 1 - 12 are not speciﬁed here as they are dependent on the SPI master. Timings A - E are speciﬁed for SPI slave.
PAGE 16
ZED-F9T - Data sheet Since the maximum SCL clock frequency is 400 kHz, the maximum bit rate is 400 kbit/s. The interface stretches the clock when slowed down while serving interrupts, therefore the real bit rates may be slightly lower. The I2C interface is only available with the UART default mode. If the SPI interface is selected by using D_SEL = 0, the I2C interface is not available.

ZED-F9T - Data sheet 5.4 USB interface The USB 2.0 FS (Full speed, 12 Mbit/s) interface can be used for host communication. Due to the hardware implementation, it may not be possible to certify the USB interface. The V_USB pin supplies the USB interface. 5.5 Default interface settings Interface Settings UART1 output 38400 baud, 8 bits, no parity bit, 1 stop bit. NMEA protocol is enabled by default and GGA, GLL, GSA, GSV, RMC, VTG, TXT messages are output by default. UBX and RTCM 3.
