CXA3355TQ
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.
(Applications: GPS RF 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 ≈ 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
Package
48-pin TQFP (Plastic)
Structure
SiGe BiCMOS monolithic IC
