GPS Down Converter IC
CXA3355AER
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.
(Applications: GPS down converter IC)
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)
