HDM1216 is easy to integrate with its leadless chip carrier (LCC) packages.1.2Structure descriptionFigure 1-1 HDM1216 structureThe HDM1216 is insisted of the follow parts:HD8020RF matchingPowerTCXOOSC 32.768KHzInterfaces: UART/USB/I2C/SPIIO Pins: PRRSTX/ PPS/EXTINT/PRTRG材器电中2 Function Description2.1 HD8020HD8020 is a highly integrated standalone GPS/GNSS (GPS, BDS, GLONASS, GALILEO) positioning chip developed to provide excellent location services.Figure 2-1 HD8020C11RF_IN2.2 RF matching circuitThe RF part is a L matching circuit. D1 is for ESD protection.Figure 2-2 RF matching circuit2.3 Connecting powerHDM1216 positioning modules have up to three power supply pins: A VD33DC, A VD33BAK and A VDUSB.2.3.1 A VD33DC: Main supply voltage (3.3V)The A VD33DC pin provides the main supply voltage. During operation, the current drawn by the module can vary by some orders of magnitude, especially if enabling low-power operation modes. For this reason, it is important that the supply circuitry be able to support the peak power for a short time.2.3.2 A VD33BAK: Backup supply voltage (3.3V)If the module supply has a power failure, the A VD33BAK pin supplies the real-time clock (RTC) and battery backed RAM (BBR). If no backup battery is connected, the module performs a cold start at power up.Avoid high resistance on the A VD33BAK line: During the switch from main supply to backup supply, ashort current adjustment peak can cause high voltage drop on the pin with possible malfunctions. If no backup supply is available, connect the A VD33BAK pin to A VD33DC.As long as power is supplied to the HDM1216 module through the A VD33DC pin, the backup battery isdisconnected from the RTC and the BBR to avoid unnecessary battery drain. In this case, AVD33DC supplies power to the RTC and BBR.C11RF_IN中电器材2.3.3 A VDUSB: USB supply voltage (3.3V)A VDUSB supplies the USB interface. If the USB interface is not used, please leave it open and delete C8.2.3.4 ANT_BIAS: Output voltage for active antenna (3.3V)ANT_BIAS supplies power to an active antenna or external LNA.2.4 TCXOFigure 2-3 TCXO2.5 OSC 32.768KHzFigure 2-4 32.768KHz2.6 Pins and InterfacesFigure 2-5 Pins and InterfacesY1PPS SPICXUSBDP USBDN EX TINT ANT_BIAS PRRSTXRF_IN ANT_ON SPIDI SPIDO SPICK UIN0UOUT0SCL SDA R40RPRTRG M1HDM1216GPIO91PRTRG 2GPIO133GPIO144USBDN 5USBDP 6AVDUSB 7PRRSTX 8ANT_BIAS 9GND110RF_IN 11GND212GND313GPIO214GPIO615GPIO716GPIO817GPIO418GPIO519TX D020RX D021AVD33BAK 22AVD33DC 23GND424AVDUSBAVD33DCAVD33BAK 中器2.6.1 UARTThe Universal Asynchronous Receiver / Transmitter (UART) provide serial communication with external device.

Please pay attention to the RF matching part, DCDC part and TCXO part.材器电中Figure 3-2 PCB Layout3.3.2 RF 50Ω matchingThe RF line must be 50Ω matching and as short as better. Put the matching parts nearest to the RF_IN pin. The GND/VCC/BOTTOM layer behind the RF part must be an integrity GND net without any other signals. Put some GND via along the RF signals for better performance. Put an integrity shape on the silkbottom layer for protection.Figure 3-3 RF 50Ω matching3.3.3 TCXOThe TCXO_IN signal should be as short as better. Put TCXO away from noisy part.Figure 3-4 TCXO中电器材3.3.4 For Better DCDC PerformanceFor better DCDC performance, place the DCDC 3.3V capacitor GND pad nearest to the 1.5V capacitor GND pad.Figure 3-5 DCDC part中电器材3.3.5LayersThe PCB for HDM1216 module has four layers. They are TOP, GND, VCC and BOTTOM. All the parts are putted on the TOP layer. The GND layer should be the important integrity GND net without any other net lines for the best RF and noise performance. The power net lines are on the VCC layer.3.3.5.1The TOP layer材器电中Figure 3-6 The TOP layerFigure 3-7 The GND layer中电器材Figure 3-8 The VCC layer中电器材3.3.5.4 The BOTTOM layerFigure 3-9 The BOTTOM layer3.4 Antenna3.4.1 Passive antenna designWhen a passive antenna is used, pay more attention to the layout of the RF section to reduce electrical noise that may interfere with the antenna performance. A DC bias voltage is not needed, passive antennas can be directly connected to the RF input pin, matching the impedance to 50Ω. Sometimes, a passive matching network to match the impedance to 50Ω is needed.中电器材3.4.2 Active antenna designActive antennas have an integrated low-noise amplifier. Active antenna requires a power supply. The power supply to the active antennas will contribute 5-20mA to the GNSS system power consumption. The ANT_BIAS pin is for the LNA power supply. The ANT_ON pin is for the EN signal of the LNA.4 ESD precautionsGNSS positioning modules are sensitive to ESD. Whenever handling the receiver, particular care must be exercised to reduce the risk of electrostatic charges. In addition to standard ESD safety practices, the following measures should be taken into account. Add ESD Diodes to the RF input part to prevent electrostatics discharge.Do not touch any exposed antenna area. Add ESD Diodes to the UART interface.中电器材。
