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 “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.

 

Features NT1065 RFIC

  • Single conversion superheterodyne receiver
  • Four independent configurable channels, each includes preamplifier, image rejection mixer, IF filter, IFA, 2-bit ADC
  • Signal bandwidth up to 31 MHz supports GNSS high precision codes such as P-code in GPS or wideband E5 Galileo
  • Dual adoptable AGC system (RF + IF) or programmable gain
  • High dynamic range with 1dB compression point more than -30 dBm
  • Analog differential output with two options of voltage swing 0.2/0.47 Vp-p and 0.4/0.98 Vp-p (sine wave/noise) or 2-bit ADC digital output data
  • Two independent fully integrated synthesizers with flexible LO and CLK frequencies selection (“A” and “B”)
  • Embedded temperature sensor
  • SPI interface with easy-to-use register map
  • Individual status indicators of main subsystems (available in SPI registers) and cumulative status indicator (AOK, available both as a separate pin and in SPI registers)
  • 10 x 10 mm QFN88 package
