CXA3355TQ - GPS Down Converter IC

Description

The CXA3355TQ is an IC developed as a GPS RF down converter.

This IC realizes a reduction in the number of external parts by integrating LNA, image rejection mixer, IF filter and PLL/VCO parts, such as inductor and variable capacitors.

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 ≈ 4.0dB ‹ On-chip VCO and PLL ‹ Selectable TCXO frequency ‹ On-chip LNA (NF = 2.0dB) ‹ Image rejection mixer ‹ On-chip IF filter, and an external filter can be connected as an option for further band narrowing. ‹ 1-bit IF output Packag.
