GPS Down Converter IC
CXA3355ER
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.
44 pin VQFN (Plastic)
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

• 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
