CXA3355ER - GPS Down Converter IC

General Description

The CXA3355ER is an IC developed as a GPS RF down converter.

This IC realizes a reduction in the number of external parts by integrating an LNA, image rejection mixer, IF filter, PLL and VCO (L, C) into a small package with low current consumption.

Key Features

  • Includes all functions required for the GPS down converter.
  • Low voltage operation: VCC = 1.6 to 2.0V.
  • Low current consumption (active mode): 11mA (Typ. at VCC = 1.8V, IF ≈ 1MHz).
  • Low current consumption (power save mode) < 1µA.
  • Total gain ≈ 100dB.
  • Total NF ≈ 4dB.
  • On-chip VCO and PLL.
  • Supports typical TCXO frequencies (13MHz, 16.368MHz, 18.414MHz, etc. ).
  • On-chip LNA (LNA NF: 2.0dB).
  • Image rejection mixer.
