com 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) 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) Sony reserves the right to change products and specifications without prior notice.
