CXA3355AER - GPS Down Converter IC

Description

The CXA3355AER 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.

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 ‹ On-chip IF filter, and an external filter can be connected as an option for furt.
