Dl-2222n-Gcmr GPS -165dBm Tracking Sensitivity GPS Smart Antenna Module

The Delin DL-2222N-GCMRis a completeGPS engine module that features super sensitivity, ultra low power and small form factor. The GPS signal is applied to the antenna input of module, and a complete serial data message with position,velocity and time information is presented at theserial interface with NMEA protocol or custom protocol.Its -165dBm tracking sensitivity extendspositioning coverage into place like urban canyons and dense foliage environment where the GPS was not possible before. The small form factor and low power consumption make the module easy to integrate into portable device like PNDs, mobile phones, cameras and vehicle navigation systemsApplicationsLBS (Location based Service)PND (Portable Navigation Device)Vehicle navigation systemMobile phoneFeaturesBuild on high performance, low-power MediaTek MT3339 chip setUltra high Track sensitivity: -165dBmExtremely fastTTFFat low signal levelBuilt in high gain LNALow power consumption: Max 28mA@3.3VNMEA-0183 compliant protocol or custom protocolOperating voltage: 3.0V to 5.0VOperating temperature range:-40to85ºCPatchAntennaSize:18.4x18.4x4mmModule Size: 22.1x22.1x8.6mmCommunication type: UART/TTLRoHS compliant (Lead-free)ParameterSpecificationPowerSupplySupply voltage: 2.8V~4.3V Typical: 3.3VPowerConsumptionAcquisition: 28mA @VCC=3.3VTracking: 25mA @VCC=3.3VStandby: 2.0mA @VCC=3.3VBackup: 15uA @VBAT=3.3VReceiver TypeCode 66 search channels, GPS&QZSS L1 1575.42MHz C/A22 simultan ous tracking channels
