CXA3355ER Datasheet | Sony Semiconductor Solutions

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): 11m A (Typ. at VCC = 1.8V, IF ≈ 1MHz) - Low current consumption (power save mode) < 1µA - Total gain ≈ 100d B - Total NF ≈ 4d B - On-chip VCO and PLL - Supports typical TCXO frequencies (13MHz, 16.368MHz, 18.414MHz, etc.) - On-chip LNA (LNA NF: 2.0d B) - 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 Applications GPS down converter IC Structure Si Ge Bi CMOS monolithic IC 44 pin VQFN...
