CXA3355ER GPS Down Converter IC Description The CXA3355ER 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.
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) • Im...
