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 “A” while PLL “B” 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 “A”. 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
NT1066 is a 4-channel RF Front-End IC (3 wideband IQ and 1 narrowband IQ) that covers all GNSS (GLONASS, GPS, Galileo, BeiDou, QZSS, NavIC) signals at all frequency bands. It makes possible to benefit from all the advantages of acquiring multiple system simultaneously. Channels “A”, “B” and “C” are designed with single conversion low-IF architecture, individually programmable and intended to receive L1, E1, B1, E6, B3, L2, L3, B2, L5, E5 in various combinations. IQ and image suppression modes are available, other options can be discovered in feature list. Channel “D” is dedicated to operate in S band or L2, L3, L5 bands of GNSS and has zero-IF architecture. S and L5 bands combining lets user to eliminate effectively ionospheric distortion utilizing large signal base. As alternative, channel “D” can be ‘on a fly’ software-reconfigured to receive real-time corrections data transmitted over FM, VHF and UHF bands.
NT1066 does also integrate 4 fractional-N synthesizers that have the common reference frequency input. Wide list of attractive features and high level of customization make NT1066 capable to meet a demand of researchers and OEM developers in special applications: high precision positioning, goniometric, driverless car systems, professional drones and related areas.
