Description
NT1065 is a four-channel RF Front-End IC for the reception of Global Navigation Satellite System (GNSS) signals (GPS, GLONASS, Galileo, BeiDou, NavIC, QZSS) and also signals of satellite-based augmentation systems like OmniSTAR at all frequency bands in various combinations: L1, L2, L3, L5, E1, E5a, E5b, E6, B1, B2, B3. Galileo E5 band as well as BeiDou B1, B2, B3 (phase 3) band can be obtained as entire signal with two channels fed by the same LO and then restored in digital domain to true complex data. As a benefit one can discover wide possibilities of improving the positioning accuracy down to centimeter range without taking RTK technique. Each setting, including output signal frequency bandwidth, AGC options, mirror channel suppression option, etc., can be set for every channel individually. NT1065 includes two fully independent frequency synthesizers. Channel#1 and channel#2 are supplied with LO signal generated in PLL โAโ while PLL โBโ is assigned for channels #3 and #4. For specific applications there is an option to feed all four channels with single LO source from PLL โAโ. This powerful toolkit is accompanied with very simple and easy-to-use register map. All the functionality allows application of NT1065 in high precision GNSS based positioning, goniometric, driverless car systems and related branches.
