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)
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 further band narrowing.
1-bit IF output
Antenna sense function
Structure
SiGe BiCMOS monolithic IC
Package
44 pin VQFN (Plastic)
